SecuExtender activation problems

emanuele_mariani

I am trying to install SecuExtender VPN Client_IPSec_SSL_VPN_7.7.50.008(subscription_based) on three different company PCs. However, during the activation process, I keep getting Error 54: "The activation server is unreachable."

I have tried disabling both the antivirus and firewall without success. I also tried using both the corporate network and my phone's mobile hotspot, with no luck.

After reading other posts, I ran nslookup tgbosa.com, which returned a positive result. The Windows version is 25H2.

At this point, I'm not sure how to proceed.
