I've began facing a strange issue on the BSNL network (FTTH). Some of the sites that I used to access daily (including some of our own test servers) aren't accessible anymore. The interesting thing is that I can ping these servers and get a response, however when I try to access them using browser, I get the following error message: This site can’t be reached The connection was reset. Try: Checking the connection Checking the proxy and the firewall Running Network Diagnostics ERR_CONNECTION_RESET I've already tried altering the DNS but didn't work. I thought the DNS cache could be a problem and cleared it on my machine - still didn't help. What's working though is accessing these sites using mobile data connection. I can connect to the sites using Jio's mobile network, but that connection isn't useful for all my regular upload and download activities. I've faced this issue in the past but can't recall the exact way I fixed it. Would really appreciate if someone can help with it. If it's all from BSNL's side, I hope they resolve it.
