Why not version 7.8.0

[joenzx]

Deployed Skywalking on K8S, tested versions 7.5 and 7.6, and was able to access the home page, but when the image was changed to 7.8, the home page was inaccessible。

If the image above is 7.5 or 7.6, it will run fine.
If the version is 7.8, the page cannot be accessed. The following error message is displayed

What you posted has nothing relating to ElasticSearch server.

What you posted has nothing relating to ElasticSearch server.

I don't know the exact reason. The reason is that I can directly access the home page using Apache/Skywalking - OAP-server: 8.6.0-ES7. Other configurations remain unchanged

Check the doc, rather than following some unknown version blogs.
We changed webapp container from Zuul to Spring Gateway v2. So a http:// prefix is required.
