My Gateway does not show up in Phoscon

I have phoscon installed on an raspi 4 - it worked for about 3 years without any problems. But suddenly (maybe after I installed raspi updates via apt-update/apt-upgrade) my Gateway (Raspbee II) does not show up on the Phoscon-App anymore. Whenever I call the IP-address of the raspi (as I did always before) I get Phoscon-App Login page with an empty page (no tile is shown). I also have a NodeRed installation on the same raspi which uses the Phoscon-Node with severeal devices - these installation runs without any problems. So the physical connection between raspi and RaspBee II should be fine. Also the service is running on the raspi without any errors.
Can you help me please?

Many thanks!!

Change the url to login2.html instead of login.html

Ok, that’s it. Thanks for the hint! And why is this suddenly necessary?

Thanks!

Some bug introduced. Should be fixed in 2.28 iirc

I have the same problem with version 2.28.1,
it’s a shame no update via sudo apt-get update
but the link to the gatway Phoscon App - Login works
link to to the Phoscon-GW doesn’t work
