If you are getting no response then you have something blocking the connection. You can paste the log in the topic if you are not sure as its not really any sensitive information to show.
So if you can answer these questions that we might be able to know how you got it.
What antivirus you got?
Since when are you getting this problem?
Did you change your internet provider/modem?
1. Try with other device
Try using your phone or a different computer on same connection if you can access the website/forum - > t4 one
- Also can be checked as @Semirak said with a proxy though its better to check with a different device. You can try both.
2. Try restarting your router/modem
If you have router/modem you should be able to restart it by turning it off and on again.
3. Try flushing your DNS
typing in console aka Command Promt ipconfig /flushdns
4. Try changing your DNS
Cloudflare DNS, 1.1.1.1 and 1.0.0.1 https://1.1.1.1/
5. Try Using VPN
A good free VPN Software you can try is Windscribe.
If 1. works then try 2. and 3. also 4. if they don't work try 5.
It may be a provider blocking a certain host though that wouldn't make sense.. Are some websites blocked for your? Like Facebook, Youtube or such? Like have you ever had this issue on other websites?
The main reason i stated all of these is that using a VPN on long terms is not good. So lets try to find a way to fix the issue ;)
p.s. harzad we miss u ig i wanna rek u
