Hi @agabima ,
If the reason for your server to be inaccessible is related to the Alteryx Service not running or something similar to that, then no.
If the only issue is the connectivity between your computer and the Gallery, then yes.
Best,

Not really sure about the issue. The last information I got was due to remediation of Microsoft HTTP/2 Protocol Distributed Denial of Service (DoS) Vulnerability in the server.
