Remote Access Problem

[zetetic 5]

This would be useful functionality. For some reason every few days I can't connect to Emby from outside my network, but I can still connect to my Jriver server running on the same PC. Once I restart Emby it is fine again.

Hi @zetetic let's try to get to the bottom of this. Can you please attach the emby server log from when this happens?

Thanks !

No problem. Looks like there is a lot of info in the logs I probably do not want on a public forum. There are a lot of port mapping errors which seem a likely problem.

These keep repeating in the logs. Is this enough data to know something?

Coincidentally, the problem was occurring right now and I think I just solved it myself by manually adding the port mapping in my router.

I very much appreciate the time to consider this.

HI @zetetic so are you all set now, or are you still having an issue with this?

[zetetic 5]

Looks like port mapping sorted it out, thanks

Thanks for the feedback!
