External access to Valetudo is blocked

Are you already using Valetudo?

Yes, for a few months

Your questions

I have been using Valetudo for a long time, I needed to change the router's IP address and DHCP ranges, the wifi SSID and password have changed, the Roborock 5 connects to wifi, I see it on the network, but the UI does not show up for me, only this error: External access to Valetudo is blocked.
Valetudo has the correct new address, but can't access UI.

Make sure that you're using a DHCP range that is part of these: https://en.wikipedia.org/wiki/Private_network#Private_IPv4_addresses

I changed only the ranges from 10.10.10.xx to 11.11.11.xx.

11.11.11.x is not part of the list of valid private IPv4 ranges that I've linked you.
