@stevedennis Thanks a lot for your feedback. I ran that query, and here are some results from today's failure:
"An error occurred in the web application: Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

Briefly, I wanted to provide you with a history of this issue. We've been running the tool for a few years now, and out of no-where about 6 months ago, this happened. But somehow after around 2 weeks, it suddenly allowed us to start the service on Windows. Now we've been having this problem for about 4 weeks.

Here's the error we see when trying to run the Otter service EXE via the command line:

Thanks a lot for your time and help looking at this. I've spent hours on this so far haha.

Thanks - Justin

Hello,

We are running into an issue where we are trying to start the agent service, and we get a very vague error message before the Agent times out. We've checked all permissions on the SQL Server side, and we have tried restarting the server, as well as the SQL Server. There isn't anything clear to our team that indicates any particular issue. Any help would be greatly appreciated.
Here's the error:
