Remote Access stopped working - despite via iPhone App

Server Version#: 1.25.1.5286
Player Version#: Web Browser

I already asked to refresh certificates w/o any change. Issues appeared a few weeks ago - but I can’t classify since I use usually Wifi. QNAP SW has changed, and router too (fritz box). Ports are open, but I tried to change, and set manually. Logs attached.

Thank you in advance, if anything is missing, tell me.

Check the static IP reservation (if you have one).
Also check the QNAP IP address (if you set it static – best).
Else, check the minimum DHCP lease time.

The machine is constantly resetting the adapter

If the machine is connected via WiFi – strongly recommend using ethernet.

Hello ChuckPa, thanks for pointing out the network issues. I had a second IP via VLAN code over my usual IP for the QNAP, that worked till now - but I have disabled that.

I think I do not have a static IP reservation - that is to be negotiated w/ internet provider right?
QNAP IP is static, and I have disabled the VLAN.
I do not use wifi.

Accessibility is only green for 5 seconds, and turns red.
I am not able to see computer via canyouseeme.org

I read to check for double NAT I have to write down WAN IP and check for IP shown at canyouseeme.org - but my Router shows just an AFTR-Gateway with IPv6 ?!

Any suggestions - I already asked my internet provider if they have changed anything regarding my setup - waiting for an answer

It’s normal or it to turn green (in anticipation of success).

If it doesn’t get confirmation then it turns red.

you only have IPv6 IP at the router WAN IP?

Looks like DS-Lite Tunnel for IPv4 - maybe they took me off of IPv4 list w/o notification - still waiting for provider to reply.
In Plex I ticked the box for IPv6 support - won’t that help?

No. Plex has not yet implemented full IPv6 support. (Remote Access side)

The server code is written and working to handle IPv6 now.

I haven’t tried this but it should work normally -

  1. FQDN access to a dual-stack server (IPv6 & IPv4)
  2. Computer , also with dual-stack (IPv6 & IPv4) .
  3. Open the Plex/web client using the FQDN of that remote host

When connecting to any host, If both IPv6 and IPv4 are avaiable, IPv6 is preferred.
This is how almost everything is configured now. IPv4 is the fallback
