While scraping some sites with the requests package in python I came across these 2 Http Connection error's
- Name or service not known
ConnectionError: HTTPConnectionPool(host='1xbet666041.top', port=80): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f04cd03ab10>: Failed to establish a new connection: [Errno -2] Name or service not known'))
- Temporary failure in name resolution
ConnectionError: HTTPConnectionPool(host='1xbet666041.top', port=80): Max retries exceeded with url: / (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7fb9bacf7f10>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')
Can any one please explain the difference between the 2 ?
Notice that I got these 2 different errors when using the same domain. The difference was that the first get call was made from DataBricks and the other from google collab.
Thanks.

Name or service not known
A name resolution has been done, and it succeeded in getting a reply, but the reply was: "this name has no IP address". So it is a positive assertion on a negative result.
Temporary failure in name resolution
No name resolution was possible at all, so it is a negative assertion on the possibility of resolving that name.

Yes, but using which nameserver(s)?
Assess your domain correct DNS configuration using a tool like DNSViz online. Any error has to be fixed, and warnings too.
