Job stuck in "Scheduled" state

Hey,

for any reason my scheduled jobs won’t run. Instead, the “StateId” column keeps increasing → Started with 3 and now it is at 10? The State table shows me only a truncated error message, that “The type …IMyService …” → “Can not change the state to ‘Enqueued’: target method was not found.”. However, this method exists and runs without problems on my local machine? Libraries are also at the same version.

This behavior only occurs on the remote server - if I start my ASP.NET Core application locally everything works fine.

I am using an old version 1.7.7 with MySQLStorage.
Any help is really appreciated!

BR,
