AH00898 Error reading from remote server returned by

IngoPohlschneider
Hello everyone,
I am having trouble with some HTTPS services deployed via WAF.

Previously those services were deployed using DNAT.

When accessing the URL I get and Proxy error

This is what the log shows:

I masked some information in 

This happens only with this subpath. There is another portal running on this webserver (same real and virtual server) and thats running smoothly

Any ideas?

WAF is kinda hart to debug since the logs give not much of a clue what is the issue [:(]

best regards

    Hello
    I am sporadically getting the error on other sites as well. I don't know if maybe timeouts are the problem causing this issue?
