Hi,
Today I changed my mesh modems. With the new modems, the SSID and PW remain the same as with the old modem. All my other hardware automatically connected to the new modem, whether via wifi or via a cable.
Yet not my HASS (installed on the HA Blue, all updated)! Rebooting does not change anything
Update: HASS automation do work, but I do not get access to the UI anymore. The phone app indicates that the SSL-handshake cannot be executed; my workstation indicates DNS_PROBE_FINISHED_NXDOMAIN
I’m guessing the security changed between the new and old router? TKIP/WPA/WPA2/etc… Something is likely different… besides the BSSID obviously. Also are you sure it didn’t connect and simply grab a different IP address since its a new lease…
Sounds like a DNS issue on your Home assistant/network. like it can’t resolve. Did you use a static dns server that is not contactable anymore? Like your router itself?
You should be able to access it by https://<your ip number>:8123 from a normal browser; it will give you a warning, but it will allow you to open… (in contradiction to IOS, which does not allow you to open invalid certificates)
Maybe from there you can re-join the wifi and/or set another IP address?
Not sure how many devices you have (and of how many you know it’s IP)
But just use an IP scanner to see which IP’s are alive?
f.e. https://angryip.org
By the looks of it, you can also check a port…
so just check which IP listens on port 8123?
SOLVED. It appeared the new modem changed the subnet. The subnet of HASS did not change with the modem (because of Nabu Casa?). So I changed the network subnet to match the old one used by HASS. Now all works again.
Hi, do you got some print screens? Facing a similar issue with a forced move to Ziggo Smartwifi. SSID and PW remain the same. Now Im no longer able to access the UI anymore. Also not able to access HA via SSL.
SSID and password remain the same, other hardware can connect to wifi. Set up port forwarding per instructions, switched offf UPnP. IPv4 addressed for HA is reserved. DHCPv6 stateless. Automation seems to work still.
Did you change settings in your modem? If so, how?
