i think the issue might be because it enters token like this <token> and not like this token , because if i try and paste that url in browser to download json and enter my token, then i can see the json perfectly

Error Code 520 indicates a Connection Failure, possible due to TLS Interception - Not a Bug in Factorio as such. You can try a VPN service or see if other API endpoints work - but you may be out of luck, sorry.

It is possible/likely that Version 2.0.55 added verification for the Multiplayer APIs in the client itself. You would still be able to play “Offline” on your local LAN, or directly connecting to a server with Verification disabled.

Good Luck!
