Hi there,
Ah’ Nice to see it… LOL 
I have seen this b4, it was something related to the settings or browser link. It should work if I’m remembering correctly.
Have a LQQK at this XIAO ESP32S3 Sense camera not working - #8 by PJ_Glasso
does the web page for camera server work?
Just a long shot but still worth noting if it works.
HTH
