Opera redirects my site https://www.klimalex.de/ to 127.0.0.1 (disk cache)

Hello,

I operate the ecommerce website https://www.klimalex.de/.

On multiple independent Windows systems (including Windows 10 and Windows Server 2019), Opera Stable (versions 131.0.5877.24 and 131.0.5877.55) redirects my site to http://127.0.0.1, showing ERR_CONNECTION_REFUSED.

Observations:

• The site is reachable in Chrome, Firefox, and curl.
• curl with an Opera User-Agent correctly returns HTTP/1.1 200 OK and resolves to 178.250.9.119.
• DevTools Network in Opera shows:
  • www.klimalex.de → 301 Moved Permanently (from disk cache)
  • Next request → 127.0.0.1 → net::ERR_CONNECTION_REFUSED
• This affects multiple systems including VMs and external PCs.

Impact:

• This prevents Opera users from accessing a live ecommerce site.
• It seems Opera is using a cached permanent redirect incorrectly.

Attached screenshots show the error page, DevTools Network with 301 from disk cache, and curl outputs.

Steps already tried:

• Clearing Opera cache and site data
• Testing with a clean profile
• Multiple machines and Windows versions

Please investigate why Opera caches or applies this incorrect redirect to 127.0.0.1 and how this can be fixed.

Thank you.

@Anonymous-Opera When I try to open the page, I get:

Forbidden
You don't have permission to access this resource.

Tried on Opera, Chrome, Edger and Vivaldi

Thanks for testing.

The “403 Forbidden” result is likely caused by our country/IP blocking rules, because we intentionally block traffic from several countries. If you are accessing the site from a blocked region, the 403 response is expected and is unrelated to the Opera-specific redirect issue.

If possible, please test again from a German IP address or via a VPN endpoint in Germany. The issue I am investigating is specifically this:

Chrome / Firefox / curl: website loads correctly
Opera Stable 131.x on Windows: redirects https://www.klimalex.de/ to http://127.0.0.1 from disk cache

So your 403 result may be a separate access-control case.

@Anonymous-Opera Update: The issue appears to be fixed for me in Opera One 131.0.5877.74. The problem occurred in 131.0.5877.24 and 131.0.5877.55. According to Opera’s download index, 131.0.5877.74 appeared around 20 May 2026, and 131.0.5877.97 appeared around 22 May 2026.
