Unrecognized symbols in confluence log

[Commercial Account Easy Technology]

I'm trying to Configure Atlassian JIRA Server in Confluence.

I've created in JIRA - JIRA User Server for Confluence

In Confluence I've entered all data of JIRA User Server. But have an error with unrecognized symbols:

How to correct these errors:

1. How to configure logging in Confluence
2. What's the problem with connecting Confluence to JIRA User Managment?

P.S.

Applink between JIRA and Confluence already configured and work well.

It looks like you are surfing http to a https connection. The binary data you are seeing is in fact the SSL certificate.

This happens when port 80 is forwarded to 443 without telling the modproxy it needs to do SSL proxying, basically blindly forwarding port 80 to 443. When you create the link make sure it's done either or a http port that serves http, or on a https port that serves https. This applies both to "User servers", "User directories" or Application trusts.

Good luck.
