Arknights: Endfield support: contact, account, payment and bug reports

The right channel already saves a round trip

When an account stops syncing or a payment stays pending, hunting for a random social media account wastes time and sometimes exposes sensitive data. Arknights: Endfield has three confirmed channels: the in-game form, the account center on the official website, and the endfield_cs@gryphline.com address.

When the account is still accessible, open the in-game form via Settings → Platform & Account → Contact Customer Support. GRYPHLINE then receives a request attached to the context of the relevant account and server.

Which channel to use?

In-game support

Use it for a bug, blocked progression, a missing item or a problem tied to the currently connected account. Pick the most precise category available; an “other” ticket often requires extra triage.

The official account center

If the client will not start or you can no longer access your account, log in to the official Arknights: Endfield website and open Account Center, then Contact Customer Support. This method is also mentioned in official technical notices.

The email address

For other requests, GRYPHLINE lists endfield_cs@gryphline.com. If possible, use the address tied to the account. The email accepts several screenshots, an error log and a masked payment receipt.

Social networks can signal a general outage, but they are not a safe place to send a UID, an email address, a receipt or a transaction number.

Information to prepare before sending

An effective ticket lets someone else reproduce or trace the incident. Prepare the following.

• Your UID and server, without posting this data publicly.
• The exact platform: PC, PS5, Android or iOS.
• The device model and the OS version.
• The date and time of the incident, with the time zone.
• The sequence of actions that triggers the problem.
• A full screenshot, with the error code readable.
• For a purchase, the transaction reference and the payment channel.

Then describe the expected result and the observed result. “The game does not work” is hard to diagnose. “After selecting Continue on the Europe server, the client returns to the title screen with code X” gives a starting point.

Never send your password, a one-time login code or your full bank card details. A payment proof must hide the information not needed to identify the transaction.

Account and sync: check before opening a ticket

Progression syncs across platforms when the same account and the same server are used. A save that looks empty can therefore come from a different login method or a server selected by mistake. For the technical side of multi-platform play (storage, requirements, cross-save), the platforms, requirements and cross-save guide gathers the official information.

Before contacting support, note the method used on the first device, the original server and the UID visible on the correct save. Do not unlink accounts at random to try to fix the problem: that manipulation can complicate the diagnosis.

Payment: do not buy twice right away

In case of a charge without delivery, keep the receipt and check the history of the channel used. Avoid repeating the purchase while the status of the first one is unclear. Tell support the product, the amount, the currency, the platform, the time and the transaction reference.

GRYPHLINE also reminds players not to use unauthorized top-up channels. The risk is not limited to a disputed transaction: the account can face measures if irregular purchases are detected.

Graphics bug or PC performance

Attach the graphics card, the driver version and the DirectX mode used. Official notices may already contain a temporary workaround: for an issue tied to certain NVIDIA driver versions, GRYPHLINE had for example recommended DirectX 11 mode or rolling back to a previous driver.

So check the official announcements before sending. If the incident is known, apply only the procedure published by the publisher and mention its result in the ticket.

After sending

Keep the request reference — the ticket ID shown in the confirmation — and reply in the same thread if support asks for more information. Opening several identical tickets does not document the problem any better. If the situation evolves, simply add the new time, the new error code or the result of the requested test.

Support cannot always fix a version bug immediately, but a precise report can at least be forwarded to the relevant team. That is the difference between a legitimate complaint that stays vague and an incident that can actually be worked on.

Ready-to-fill message template

Use the following structure, for example.

Subject: [Platform] Issue type - UID - server.

UID and server: to fill in.

Device and OS: model, Windows, Android or iOS version.

Date and time: with time zone.

Steps: action 1, action 2, action 3.

Observed result: error code or exact behavior.

Expected result: what the client should have displayed.

Tests already done: restart, other network, file check.

Attachments: screenshots, short video or masked receipt.

This format avoids overly long paragraphs and lets customer support forward the technical elements without reinterpreting them. For an intermittent incident, add its frequency: at every launch, once in three, or only after an update.

Platform-specific checks

On PC, specify whether the game goes through GRYPHLINK, the Epic Games Store or GeForce NOW. For a graphics crash, attach the graphics card, the driver version, the RAM amount and the DirectX mode. The GRYPHLINK launcher offers a DirectX 11 option intended for compatibility problems; specify whether enabling it changes the result.

On Android, note the exact processor model when available, the OS version and the free space. A screenshot of the app info screen can complement the ticket. On iOS or iPadOS, provide the device model, the OS version and the free space before downloading the resources.

On PS5, note whether the problem appears before or after connecting to the server. For an update, first use the Options → Check for Update command from the home screen. An account incident must mention the Endfield UID; the PlayStation gamertag alone is not always enough to identify the save concerned.

Protecting the account during resolution

GRYPHLINE advises against sharing, transferring and selling accounts. A supposed agent asking for a password or a one-time code is not following the normal procedure. Official replies must stay in the ticket, the account center or an exchange with a Gryphline domain address.

For a disputed purchase, send only the necessary items: transaction ID, date, amount, currency and product. Mask the full card number, the cryptogram and any other command visible on the receipt.

The Google Play Store also displays a general publisher customer support address. For an Endfield-specific problem, prefer the in-game channel or endfield_cs@gryphline.com, both cited in the game’s official notices. This distinction reduces the risk of the case being redirected between services.

When the problem affects many players

A server outage or a bug introduced by a version is not fixed on a single device. Check the official news and compare the error code before reinstalling several dozen gigabytes. If a notice confirms the incident, keep your ticket only if your case persists after the announced fix.

Without a notice, an individual report remains useful. Indicate your region, your internet provider, your server and the exact moment the connection fails. Several structured tickets around the same code and the same time give the team a more usable signal than a series of public messages without technical context.
