A lot of Arc Raiders players are running into a frustrating problem with the “A Toxic Trail” quest.
You finish all the objectives, extract like you’re supposed to, and expect the quest to complete — but instead, the game refuses to register it.
When you try to claim the quest rewards, an Unknown ARB error pops up, and the quest stays unfinished.
The worst part is that nothing is actually missing or done wrong.
The objectives are complete, the run was successful, but the Arc Raiders quest bug blocks progression anyway.
This A Toxic Trail rewards not claiming issue has been showing up for a lot of players during active play periods, which strongly points to a server-side Arc Raiders error, not a player mistake.
Quick Answer: Why the A Toxic Trail Quest Cannot Be Completed
The A Toxic Trail quest bug in Arc Raiders happens because the game’s servers fail to confirm the quest completion.
When the run ends and the game tries to claim the quest rewards, the backend doesn’t accept the update, throws an Unknown ARB error, and leaves the quest stuck as incomplete.
Nothing is wrong with how the quest was played.
The objectives were finished and extraction worked, but the Arc Raiders quest reward claim issue stops progression anyway.
Since this is a server-side validation problem, it usually can’t be fixed through normal in-game actions and requires a backend update from the developers.

What Is the Arc Raiders Unknown ARB Error?
The Unknown ARB error in Arc Raiders is basically the game’s servers failing to save what just happened.
You finish a run, everything looks fine on your end, but when the game tries to update your progress, the backend doesn’t accept it.
This usually shows up when the game is handling:
- Quest reward claims
- Quest completion checks
- Extraction-based progression updates
When the Arc Raiders ARB error hits, the server never locks in the quest completion. So even though all objectives were done correctly, the quest — like A Toxic Trail — stays unfinished and the rewards don’t go through. It’s a backend issue, not a gameplay mistake.
Why Arc Raiders Cannot Claim “A Toxic Trail” Rewards
Most of the time, the A Toxic Trail rewards not claiming issue comes down to the game’s backend, not anything you did wrong.
The quest completes on your screen, but the server doesn’t lock it in, so the rewards never register.
The main reasons this happens are:
Primary causes
- A server-side quest validation bug where Arc Raiders fails to confirm completion
- Backend desynchronization during extraction, meaning the run ends but the progress doesn’t sync
- Temporary Arc Raiders server instability, especially during busy play periods
Secondary contributing factors
- An expired login or session authentication that breaks the reward claim
- VPNs or proxies interfering with the connection to Arc Raiders servers
- Corrupted local game files that send bad data during quest completion
- Launcher or platform sync issues between the game and the account
When these combine, the result is the same: the Arc Raiders quest reward claim issue triggers an Unknown ARB error, and A Toxic Trail stays stuck as incomplete.
Quick Fix Tips
These won’t fix every case, but if the Arc Raiders A Toxic Trail quest bug is tied to a bad session or sync hiccup, these steps can sometimes push the quest reward claim through.
- Fully restart Arc Raiders and the launcher — don’t just close it, actually exit and reopen everything
- Log out and log back into your platform account to refresh your session
- Turn off VPNs, proxies, or custom DNS that might interfere with Arc Raiders servers
- Run the game normally (not as administrator), since admin mode can cause weird backend issues
- Verify or repair the game files in the launcher to fix anything corrupted
- Try extracting again if the A Toxic Trail quest can be replayed
If one of these works, the Arc Raiders quest reward claim issue usually clears right away. If none of them help, it’s a strong sign the Unknown ARB error is coming from the server side and needs a developer fix.
Arc Raiders “A Toxic Trail” Quest Bug Step-by-Step Troubleshooting Guide
1. Restart and reauthenticate
Fully close Arc Raiders, log out of the launcher, then start everything again. This refreshes your session and can sometimes clear the quest reward claim issue tied to the A Toxic Trail quest bug.
2. Disable VPNs and network filters
If you’re using a VPN, proxy, or custom DNS, turn it off for now. These can block or delay backend requests that Arc Raiders needs to confirm quest completion and often trigger the Unknown ARB error.
3. Verify the game files
Use the launcher’s verify or repair option. If any files are corrupted, the game can fail to sync progress when you try to claim A Toxic Trail rewards.
4. Update graphics drivers
Outdated or unstable GPU drivers can cause problems right after extraction, when Arc Raiders updates quest progress on the server.
5. Retry the quest if it’s available
If the game lets you replay the A Toxic Trail quest, run it again and extract cleanly. A fresh run can sometimes force a successful server validation and complete the quest.
Server Bug vs Player Issue Comparison
| Aspect | Server-Side Bug | Player-Side Issue |
|---|---|---|
| Cause | Backend validation failure | Local configuration problem |
| Error Type | Unknown ARB error | Network or file errors |
| Affects Multiple Players | Yes | Usually isolated |
| Fixable by Player | No (wait for patch) | Yes |
| Progress Restored Later | Often | Not guaranteed |
Is This an Arc Raiders Server Bug?
In most cases, yes — this A Toxic Trail quest issue in Arc Raiders is coming from the server side. When a bunch of players start hitting the same Unknown ARB error on the same quest around the same time, it’s a strong sign that the backend is having trouble validating completions.
When that happens, there isn’t much players can fix on their own. The Arc Raiders quest reward claim bug usually needs a developer-side backend update to resolve it. The best move is to report the bug with the error details and wait for an official fix, since the quest progress and rewards are handled entirely by the server.
