when using stratum with this pool software
https://github.com/sammy007/open-ethereum-pool I get on the pool server: Malformed stratum request from xx.xx.xx.xx: invalid character 'P' looking for beginning of value
on the client I get:
[16:11:28] thepool.domain.com slow/down or URL or credentials invalid
All I'm altering is the url in the Ethereum.bat file to the stratum address of the pool. nothing else changes.
using
sgminer 5.5.5-gm on windows,
If I leave the previous default url in there it comes with it works fine. not sure what end is wrong. pool or client, I can use lots of other miners just not this one for some strange reason.

Sammy's pool doesn't support the stratum implementation used in sgminer.
If you check out the issues on his Github repo there is much discussion about it and he is of the opinion the mining software should change not the pool software.
