I had the same this morning after running stable for multiple days. Have reverted to 9_2 to get is stable again.Everything appeared to be working for a few days when changing to HTTPS only, but this night everything went to the crapper again. Weirdly enough, it even persisted when I disabled the app and the HA integration. Really scratching my head here. Do the BE routers suffer the same issue?
What I mean by "went down the crapper" is that devices are randomly disconnected and reconnected, the network in general is very unstable and I get constant notifications that devices have lost the connection to the internet. Went back to 9_2 to see if it would help, but the logs are constantly chatting, changing channels for nodes, disconnecting and reconnecting devices and I have a slew of CFG80211-ERROR messages.
If you manage to get this release working for you I’m happy to hear
