I could not get the point. What do you mean by TT? Could you please provide more details to make all readers understand even if they are not familiar with the mentioned error.

I don't get, Did you really get the error or are you sharing the solution of the error?

I think he meant Türk Telekom but i don't have a clue about what he's saying.

Welcome to Texas, also hope to see you in Atlanta one day, tech is growing in southern states.

Ok. Should have been more obvious. There is a WiFi system called Turk Telekom WiFiFly but I kept getting this error on the system. It looks like they are using an old version of Squid cache.

Got this error on my flight to Houston. TT is using some old software I believe, which also have some vulnerabilities. Squid-cache Squid version 3.5.27 : Security vulnerabilities, CVEs Security vulnerabilities of Squid-cache Squid version 3.5.27 www.cvedetails.com Kod:Panoya kopyala ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://portal.turktelekomwififly.com/apsPortal/welcomePage?

It's clear now. Thank you for details.

There is no solution. I'm just sharing the error and pointing out that there might be a vulnerability.
