Question Can't use my phone's USB connexion for anything else than web browsers

[CD8-T-Lymphocyte]

Hello,

When I connect my phone to my computer via USB, I can use its internet connexion. It works very well if I go on google chrome or edge, but not a single programe apart can have access to internet.

For example, none of my 4 game launchers will connect to internet, even if I turn my firewall off.
Any idea why ?

Thanks

Your phone service provider is probably filtering everything outside of port 80 and 8080 requests when the phone is connection sharing. Call your phone service provider, or visit the tech support section of their web portal to confirm that this is, or is not, the case.
