When parsing through a proxy, the error is 502 Bad Gateway Host Not Found or connection failed. What to do?

Question

PHP

There are 1000 proxies in total.
The fact that they are all in the bath is hard to believe.
The rest of the sites are working. Only the one that doesn't have a scab.

Answer 1

Are proxies free, found on the Internet, or addresses bought for a penny? 100% proxy in the ban list.
Even paid "elite private" proxies for conditional $1-3 per month are not a guarantee of a ban.
Raise your proxies on VPS, on your IP addresses, it's more reliable.
Also google "proxy through tor", there are chances that a lot of tornodes are not in the ban, and the output nodes are constantly changing automatically, so even if at the moment there is a "bad gateway" - in a couple of minutes the node will automatically change, and access will appear.
