Can't connect to sensor startpage

my sensors is running well since several years.
But now, i can’t connect to the sensor-startpage from my local network anymore.
it says, it needs a username and a password, but i didn’t set it before.
The statuspage ist available without authentification, but not the startpage.
Any ideas?

running firmware is:
NRZ-2020-133
ST:1
SDK:2.2.2-dev(38a443e)
Core:2.7.3-3-g2843a5ac=20703003
lwIP:STABLE-2_1_2_RELEASE
glue:1.2-30-g92add50
BearSSL:5c771be

This is normal.

There is no default password, it must be activated.

There is no password reset function, you have to flash the device again.

Have you updated to the beta ?
