Internal browser not connecting to Tryhackme

Michael | Last updated: Apr 30, 2024 10:34AM UTC

Hi, I was practicing at tryhackme.com but I can not use the internal browser for it. I get an error like: Burp Suite Professional Error Failed to connect to 10.10.82.157:443 Using Firefox with FoxyProxy works just fine. What's wrong? Best, Michael

Hi Michael, Where are you running Burp - is this in the attack box or on your machine itself?

Hi Ben, on my machine using the Tryhackme VPN.

Hi Michael, When you are connected to the Tryhackme VPN and attempt to use the embedded browser are you able to browse to other public sites (i.e. can you get to https://portswigger.net)?

Yes, I can. Actually I always use a VPN and then connect to the tryhackme VPN. But, as I said, with Firefox I have no problem at all.

Hi, suddenly it's working, but I don't know why. I disconnected the general VPN and connected again, leaving the tryhackme VPN on all the time. Now it works ... ??? Any idea why?

Sorry ... I tried to replicate the process but now it doesn't work. Can't connect either with or without Proton VPN. But I can reach external webpages like google.com, etc.
