having tons of issues with CentOS 7 and it's repository, so spun up an Ubuntu 16, installed a backend.

it came up - but had a ton of problem getting the frontend to talk to it. Found out that the config.xml changes the password so i had to use that goofy password in the "mysql" install.

So when it finally talked from frontend, i thought yipee.

but i am getting these:

I checked permissions inside and it gets me this:

Looks to me like the FE is talking to the database (port 3306) but not the backend (port 6543). Is your BE on the same machine / IP as the database?

Different machines. x.x.x.54 is my backend,  58 is my FE

Is the database (server) located on the same server as your BE? The FE is connecting to the database but not the BE. As it appears to me at least.



no firewall on either.

it's the myth proto error and file permissions that also worry me

What does the BE log for the FE connection attempts? Check firewall settings (6543 and 6544) on the BE maybe.
