Websites redirect error in Webmin

When I click on my domain in Virtualmin , choose server configuration then click on Websites redirect I get the following error:

500 -
Unescaped left brace in regex is illegal here in regex; marked by ← HERE in m/^(http|https)://%{ ← HERE HTTP_HOST}(/.*)$/ at /usr/share/webmin/virtual-server/list_redirects.cgi line 20.

@juanpf,

Please tell us about your install…

OS, Webmin Version, Virtualmin Version, Theme Version, etc…

These questions are at the top of each thread for a reason.

Sorry for missing this information:

SYSTEM INFORMATION
OS: Ubuntu Linux 18.04.6 Virtualmin: 7.3-1 Pro
Webmin: 2.001 Theme: Global theme (Authentic Theme) 20.01.1

I did not have this at the top of my thread when I created the thread

After upgrading to Ubuntu 20.04.5 as suggested in a different thread my problem is now resolved, the upgrade from Ubuntu 18.04.6 to 20.04.5 does take time to complete

Hello, I have the same problem, this is presented in an installation on Alma Linux 8, so as a reference in another installation with Ubuntu 22.04 I do not present this problem, I appreciate any advice to solve it. Thank you

This issue was discussed and fixed upstream.

Hi Ilia, thank you
Fixed redirection issue on Alma Linux 8, Thanks
