DNS rebinding error

Go to solution

This week I have started getting errors when trying to connect to my local Plex Server from my local TV's, my remote access was fine!

After a lot of messing around I magaged to get them working but had to disable UPnP and it's (automatic) Port forwarding rule.

This means I have now lost external access to my server, as each time I enable it or manually confirgure the port forwarding I loose local access.

One message that kept coming up was the the router or ISP blocks DNS rebinding.

Does anyboy know if this is correct and how to fix it?

Many Thanks

I suggest you seek advice over at the PlexForums.

pippincp,Been there and all the advice points to a DNS issue either with the router or ISP (BT); hence my post on this forum.

I have just taken my server and a TV to my neighbours, and it works without hicup.
So the only things to change were router and ISP (Virgin).

One other work around suggested on the plex forums was to avoid BT DNS servers;
However I would rather use them as I pay for them and they should be capable of providing a decent service!

Is there anything I can try to fix my BT issue?

Anybody having this or a similar problem.

It would be worth trying a factory reset of the router.
After many hours of testing of Plex (with excellent support from the forum and developers) and its configuration, everything was still pointing back to BT.

I  carried out many reboots of the server, router and TV's (well turned off and on!). I tried every possible setting in Plex but no improvement.
In the end the fix was to backup the router settings, carry out factory reset and the restore settings.

The problem was instantly fixed.

I am seeing the exact same issue and will try your factory reset fix.

 

Did the problem ever come back?

I've just ttried that and it didn;lt work for me.  I am still getting the following errors on my Plex logs:

 
Apr 25, 2019 11:59:10.688	ERROR	EventSource: Retrying in 15 seconds.
Apr 25, 2019 11:59:10.687	ERROR	getaddrinfo(192-168-1-252.abcdefghijklmnopqrstuvwxyz012345.plex.direct) failed: -2
 

Any other ideas?

 

thanks,

James.
