Gradwell trunk credentials mysteriously invalid Sunday 28th Feb2024

[greenfrog]

On Sunday 28th Feb two of our clients reported their 3CX inoperative. We traced it to "invalid credentials" on the Gradwell trunk. Regenerating the passwords and putting the new creds onto the 3CX trunk brought things back.

This only occurred to 3CX Small Business systems. Ones we host ourselves were fine.

Gradwell say they had other resellers reporting the same thing, and can find no fault on their systems to cause this so say the fault is with 3CX.

Anybody else had the same issue to corrobarate this?

Hello @greenfrog

I am only guessing here but I think what you experienced was due to a registration failing on SMB.
SMB has a unique feature where if a registration fails and the server receives an error for some reason then it stops sending registration to the provider until there is a manual intervention from the user. Refreshing the registration or changing something in the trunk will trigger another registration.
This is done so 3CX does not spam the providers with invalid registration attempts and getting blacklisted in the process. So if it happens again just edit the trunk and change something and see if that fixes the issue.
