Thank you for your reply.
Yes I can connect to mysql using ssh, without any problem.
I also did permissions as *.* for user hordemgr (i dont like this, but just to test it)
Again I can connect manually, but through browser i get same error.
SME server 5.1.2 with update 1.
mysql v3.23.36
Printing, samba & squid are stopped
Thanks,
John
