Using Codebird.js to get oauth2 token cancels request

javascript

#1

Sending a Twitter api request using Codebird.js and jublo.net api endpoint using this POST,
https://api.jublo.net/codebird/oauth2/token the request always is canceled with a 522 error “Origin Connection Time-out”. This request had been working up until three days ago. Has anything changed about the Twitter API?
Is there another proxy that might be more reliable than jublo.net which is using Cloudflare?
