stripe payments stop working

I get this warning: Warning: The most recent live webhook, received at 2021-11-30 13:49:31 UTC, could not be processed. Reason: The webhook was not signed with the expected signing secret. (No live webhooks have been processed successfully since monitoring began at 2021-03-18 15:15:59 UTC.)

but I have not changed the apis or webhooks. I think the last pluging update did something and I don’t know how to fix it.

I was able to receive stripe payments until December 20 without problems.
