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.

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 cacheSo 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.

Update: The issue is still not resolved.
The problem originally occurred in Opera One 131.0.5877.24 and 131.0.5877.55. It appeared to work temporarily with Opera One 131.0.5877.74, but the same problem occurred again with Opera One 131.0.5877.97.
After several Opera updates it worked again for some time. However, the issue is now present again in:
- Opera One 131.0.5877.116
- Opera One 132.0.5905.37
Opera DevTools still shows:
- Status Code: 301 Moved Permanently (from disk cache)
- Location: http://127.0.0.1
Chrome, Firefox and curl continue to return the correct result for https://www.klimalex.de/ when tested from an allowed location.
Important note:
The website https://www.klimalex.de/ is only reachable from Germany. We intentionally block access from several countries. If you are testing from outside Germany, you may receive a 403 Forbidden response. In that case, please test using a German VPN endpoint.The issue I am reporting is specifically this:
- From Germany / allowed IP locations, Chrome and Firefox load the website correctly.
- From the same allowed location, Opera Stable redirects https://www.klimalex.de/ to http://127.0.0.1 from disk cache.
- curl returns HTTP/1.1 200 OK, including when using an Opera User-Agent.
- The problem occurred in Opera One 131.0.5877.24 and 131.0.5877.55.
- It seemed fixed in Opera One 131.0.5877.74.
- It occurred again in Opera One 131.0.5877.97.
- It also occurs in Opera One 131.0.5877.116.
- It now also occurs in Opera One 132.0.5905.37.
Please investigate why Opera applies or caches this incorrect redirect to http://127.0.0.1.

Site loads no problem in regular Opera (Opera One) 132.0.5905.37 64-bit on Windows 11 in the U.S. for me, for what it's worth.
