Unknown Error when Logging in -> Error Parsing JSON from post request?

Hello all, just today, after updating to 3.9.0, I’ve been unable to log into plexamp and recieving this unknown error. My relevant logs are as follows:

Jan 03, 2022 09:53:17.795 [0x00000bd8] DEBUG - Networking: Completed request 1: (POST https://plex.tv/api/v2/users/signin?login=-----&password=-----) with code -28 (have 0 bytes) in 15235 ms.
Jan 03, 2022 09:53:17.796 [Javascript] INFO - Networking: Error parsing JSON from request 1: Unexpected end of JSON input

Going to the URL where the app should be reciving JSON, there is just a blank XML with one error block in it:

<errors>
<error code="1005" message="The request method is not allowed for this endpoint" status="405"/>
</errors>

Any idea why this could be happening? I’ve unblocked plexamp from my firewall, so I don’t think the issue is on my end. All my other plex apps work fine.

Code -28 is a timeout. Something is blocking access to plex.tv

Thanks for your response Elan, I really appreciate it. Somehow, I was able to get past the error by changing my network adaptor to wi-fi as opposed to ethernet. Not sure what the issue was exactly with my network.

Anyway thanks again, I’m a huge fan of your software and use plexamp every day.

you’re very kind, thanks!
