Archer AX55 keeps disconnecting/logging off webinterface/tether app
Since the latest firmware update i'm having issues to manage my router. Both via the webinterface or the tether app.
Webinterface:
When i logon to the webinterface the session is automatically logged off. Sometimes after a few seconds sometimes immediatly. So it's practically not managable.
Tether app:
When connected within 1 minute a message shows up;
"Network Management Force Stopped, Another admin has begun managing the network. Do you want to continue managing the network? This wil force stop the other admin's management"
I've already rebooted the device, only tried managing trough the webinterface visa verca. Not at the same time offcourse.
Hopefully someone can help me out.
Thanks in advance!
Update:
I've found the problem 
It wasn't the firmware update, at about the same time i've installed the Home Assistant TP-Link-Router add-on. (https://github.com/AlexandrErohin/home-assistant-tplink-router) So every time it tried to poll the router my webinterface/tether app got disconnected.
After disabeling the add-on the problem was solved.
