Plex Server randomly inaccessible on Synology NAS (DSM 7)

Server Version#: 1.25.5.5492-7000
Player Version#: Microsoft Edge 4.74.1
Synology DSM Version: DSM 7.0.1-42218 Update 2

I’m experiencing an issue seemingly out of the blue on PMS on my Synology DS918+

The app is installed.

The app is running.

The app/user/service has all the appropriate file permissions.

When I log into Plex I get: “The server “XXXX” is unreachable. Make sure it’s running, double check your network, and try again.”

I cannot access PMS locally on my internal IP and port - I get: “ERR_EMPTY_RESPONSE”

I have restarted the NAS.

I have updated PMS to the latest version.

No difference.

On starting up I see the following errors in the PMS log:

I have no issues with internet access. All ports are correctly forwarded in NAT and I have no outbound firewall restrictions between PMS and the web.

Was working fine before the login API issue reported earlier tonight.

Any ideas?

Thanks,
Mike

Just did one more restart and everything appears to be working again. No changes from me.

Could this be related to the plex.tv API outage earlier?

OK to close this I think given the issue is no longer occurring. Will post again if it does.

Thx,
Mike

Definitely possible.

429 is a ‘throttled’ message. That would track with the issues earlier.
