None of these solutions work for me. From one to the other day the problem occured and there we are. I could use the solution of @efranelas for one or two times. But a day later the proxy was already broke again. And until then none of the listed proxies on the website works. One of them worked totally random but just for a few hours.
I really don’t know what to do. The errors I get with a added proxy vary very much. Sometimes it tells me
Forbidden or Bad Request or unexpected EOF or net/http: TLS handshake timeout and many more…
Any ideas?
