New connection error when processing images locally

Been using WebODM for a couple of months without any issues at all. This evening, I get a Windows update and now I am getting the following connection error. (Copied and pasted from the logs.txt file)

Connection error: HTTPConnectionPool(host=‘localhost’, port=8977): Max retries exceeded with url: http://127.0.0.1:29301/info?token=Jg6fGpl0BgUU6D (Caused by ProxyError(‘Cannot connect to proxy.’, NewConnectionError(’<urllib3.connection.HTTPConnection object at 0x000001D8AC7DA710>: Failed to establish a new connection: [Errno 11001] No address found’)))\r\n[2021-10-11 22:12:44,527: ERROR/MainProcess] worker.tasks.process_task[92a85fff-b8b6-484a-a400-59f54d6cd25c]: FAILURE FOR Task [Lafourche Parish - 10/11/2021] (dbdfd678-d762-492c-8029-0bffb43d6dbf): Connection error: HTTPConnectionPool(host=‘localhost’, port=8977): Max retries exceeded with url: http://127.0.0.1:29301/info?token=Jg6fGpl0BgUU6D (Caused by ProxyError(‘Cannot connect to proxy.’, NewConnectionError(’<urllib3.connection.HTTPConnection object at 0x000001D8AC7DA710>: Failed to establish a new connection: [Errno 11001] No address found’)))\r\n"

It looks like it is trying to access a local HTTP port at 127.0.0.1:29301 and can’t locate that port. Has anyone else run into this error?

I tried to update the program, but received some kind of certificate expired error when I did that.

Do you have a firewall enabled? Make sure you’re allowing those ports to communicate if so.

We need to fix the certificate (see Cannot update: certificate has expired · Issue #1064 · OpenDroneMap/WebODM · GitHub )

I do have a firewall enabled but it hasn’t given me any trouble at all until tonight. We are using Sentinel One and it is managed by our IT contractor. I don’t have access to the controls unfortunately.

Again, WebODM worked wonderfully last night. Zero issues. Now…nothing. The only thing that has changed is the Windows .Net update that was forced on me earlier today.
