If you're using a VPN for your work, then maybe the employer network is blocking some types of access per protocol / region.

Otherwise you'll have to check with the support of your IP provider.

(É possível que se está usando uma VPN como disse que tinha em tempos configurado, ela esteja barrando teu acesso em certos portos e / ou por regiões, mas isto é só uma ideia. Caso já não esteja usando essa forma de acesso remoto à teu trabalho, então aí melhor opção será mesmo contactar teu provedor de internet e perguntar para ele por que razão não está conseguindo aceder X-Aviation...) 

I'm not using a VPN. 

Have you tried sending an email to them? ([email protected]). They are the only ones who can help at this stage. If this does not go through then you have an issue with your IP provider or the way you internet connectivity is configured. 

The time out message your getting means the site, X-Aviation does not recognise your account the way it is configured (IP or email data). 

Thanks coastaldriver. It's certainly something with my internet because today I was away and could access the site from the phone without problems. I'll send them an email, thanks.

You could use your phone as a modem that would be a temporary fix 

I'm trying Proton VPN. Icould access the site with the VPN, so let's see if this works.

With VPN I could finally update the IXEG licence. Now starts the neverending saga of trying to find out how to solve this thing.

Contact your provider support.
