Unable to connect Brave Rewards to newly created Solana Wallet ("Something went wrong" after successful signature)

Hello Brave Team,

I’m unable to connect my Brave Rewards profile to my Brave Wallet (Solana).

The connection process goes almost to the end:

  1. I created a new Solana account in Brave Wallet.
  2. I sent SOL from Coinbase to the wallet.
  3. The associated token account was created successfully.
  4. I started the Brave Rewards connection.
  5. I accepted the privacy notice.
  6. Brave Wallet requested my signature.
  7. I signed the message successfully.

Immediately after signing, Brave displays:

“Something went wrong.
There was an unexpected error and we weren’t able to finalize the connection. Please try again.”

Additional information:

• Rewards profile is VALID (checked in brave://rewards-internals).
• Rewards State on Windows remains “Not connected”.
• The problem occurs every time on Windows.
• The same error also occurs on Android.
On Linux, the wallet connection completed successfully and Brave Rewards displayed the next BAT payout date.
• My Rewards profile was originally created in 2021.
• The Solana wallet is working correctly.
• SOL is present in the wallet.
• The associated token account was created successfully

Operating System:
Windows 11 Version 25H2 (Build 26200.8655)

Brave:
Version 1.92.139
Chromium 150.0.7871.114 (64-bit)

Region:
Luxembourg

I have already spent several days troubleshooting this issue. Since the connection works on Linux but fails on Windows and Android, it appears to be platform-specific rather than a wallet setup issue.

The same Brave Rewards profile has existed since 2021. I no longer remember whether it was previously connected to Uphold or Gemini. This old Rewards profile might still contain outdated server-side information.

Could you please help determine why the Rewards profile cannot be connected?

I have screenshots showing the error on Windows and a successful connection on Linux. As a new Community member I am currently not allowed to upload attachments. I can provide them as soon as my account is permitted to upload images.

Thank you very much.

Please reset your Rewards profile if it was previously connected to a different custodian.
