Difficulty connecting to Hassio (ip:8123) from my MAC but Linux PC ok

Hello everyone, recently been having problems accessing hassio web page
192.168.1.129:8123, from my MAC (10.15.7) , with any of it’s browsers.
From my Linux PC, running mint, with Firefox there is no problem, it works fine.

Surprisingly my MAC web connection will work if I first establish from a terminal session
an ssh tunnel like: ssh -L8123:192.168.1.129:8123 [email protected] and if I use
in the browser the url= localhost:8123 . I don’t get the error 401 unauthorized when I
click on addons like configurator or terminal, and everything works fine.

Anyone has seen that ? … comments …

Thank you
jrb.

correction: speaking to thyself, not everything works fine, if I click on terminal firefox crashes !!!
