Help me with Citrix - my desktop does not open?

Our home office is pretty knitted with the hot needle. Our department otherwise works with attendance. In an emergency, everyone should now go to their home office with their personal device. Since we have various suspected corona cases in the department, it can happen every day.

I can't get it to work. According to the instructions, I downloaded the Citrix Receiver, assigned that it should open .ica files. Then I saved the link to my desktop. But I can't get it open. When I double-click, my work environment should actually open, but it only loads briefly and then does nothing.

I have already uninstalled and reinstalled several times, made a Citrix update, installed it as an administrator. I have no idea what else I can do. Maybe it is a security setting of win10. Our IT service is permanently occupied due to the rush and is located in another state. But even the nice helper from IT-Service can't connect to my private laptop. Does somebody has any idea?

Do you have an antivirus installed? Maybe that prevents the connection.

Avira, the normal free one. I also have CCcleaner and Antimalwarebytes. Can't I get a message saying something is trying to access the PC?

With Teamviewer, he doesn't get on your computer either?

There's no telling when I will get there. The last three days could not be done, there's of course none on Sundays. We're a pretty big company
I have now deactivated all 3 of the programs mentioned - no use

The firewall ports may be blocked. You should release them.

Try these solutions:

Uninstall Avira completely, it is pointless anyway.
Open the firewall ports. You can find a complete list https://docs.citrix.com/de-de/receiver/windows/current-release/secure-communication/connect-through-firewall.html.
Temporarily switch off the firewall.
Ping the server for availability.

I'll try everything in peace, thank you very much

So I uninstalled Avira and Co, released the ports, deactivated the firewall, is of no use. How do I know the server number to ping? Sorry, I'm not that firm
