Open API ProtoOAGetAccountListByAccessTokenReq fails with Server Error, but not on all accounts

Live accounts:

1. Authorize application - ProtoOAApplicationAuthReq OK
2. Get Account List - ProtoOAGetAccountListByAccessTokenReq, some fail, some work fine
   of course, tokens are good, these accounts worked fine until 02/01/2025 and 03/01/2025
3. The ones that work OK, work fine with all parts
   Ones that fail, of course they can't go on, since no authorization
4. So, system fails on trying to get accounts list via tokens
   - just returns "Server Error"
   - I can only assume there is some problem on server side when it tries to get
    Client App Key against the token that is assigned - fails and gets generic Server Error 
   
   To repeat, tokens are fine, all were refreshed when they needed to be
   I can try refresh tokens again, or re-get them again, but that didn't solve an issue for now
