The cause is a bug in ALVAO products.

Řešení

Oprava naplánována do verze 26.3 Patch (code freeze features 2026-07-27 / fixes 2026-08-03; release 2026-08-27)

Náhradní řešení

1. Modify the hosts file on the web server (quick workaround)
   1. On the server where the ALVAO WebApp is running, open the file: C:\Windows\System32\drivers\etc\hosts
   2. Add a line with the IP address of the Sophos WAF: 192.168.x.x sophos-waf.yourdomain.local
   3. Windows checks the hosts file before querying a DNS server, so GetHostEntry returns the result immediately without waiting.
2. Create a PTR record in the internal DNS (proper permanent solution)
   1. On the internal DNS server (typically Active Directory DNS), create a PTR record in the reverse in-addr.arpa zone for the Sophos WAF IP address.
   2. Example for IP 192.168.10.50:
      1. Open DNS Manager.
      2. Navigate to Reverse Lookup Zones and find the corresponding zone (e.g., 10.168.192.in-addr.arpa).
      3. Create a new PTR record: IP 50 → hostname sophos-waf.yourdomain.local.
   3. DNS resolution will then complete within milliseconds instead of timing out.
