Hey @alihamza0173, sorry to hear you're encountering this issue. Usually, we see this occur when there is a Firewall or proxy misconfiguration that is blocking the network request. To rule out the possibility that this is a network issue, could you try connecting to a different network or temporarily disabling VPN, Firewall, and proxy you may have?

Also, try running curl -X POST -I https://accounts.google.com/o/oauth2/token to see if you'd be able to make a request to that endpoint.

hi @aalej
I was connected to my regular WiFi and was not using any VPN, proxy, or firewall while facing this issue.

I ran the suggested API request, and here is the result:

curl -X POST -I https://accounts.google.com/o/oauth2/token  
HTTP/2 400  
content-type: application/json; charset=utf-8  
vary: X-Origin  
vary: Referer  
vary: Origin,Accept-Encoding  
date: Wed, 12 Mar 2025 00:50:42 GMT  
server: scaffolding on HTTPServer2  
x-xss-protection: 0  
x-frame-options: SAMEORIGIN  
x-content-type-options: nosniff  
alt-svc: h3=":443"; ma=2592000,h3-29=":443"; ma=2592000  
accept-ranges: none  

Furthermore, I had attempted logging in several times over two days, but the problem continued. Yet, I just attempted it again today, and although it failed twice, it did manage to connect successfully on the third try.

I was connected to the same network as yesterday, so there would not appear to have been any change in the network that would have influenced the result.

Please let me know if you require any additional information. Thanks!
