Confluence HTTP Error 400

[Vadim Kovalchuk]

Hi!

We have a problem after migrate confluence from windows server to ubuntu 18.04. 

What we do:

on windows server: backup data from confluence without attachments

on new server:

1. fresh install ubuntu 18.04. 

2. fresh install confluence

3. edit config files

4. start confluence

5. restore backup data

6. copy attachments from windows server

When we open confluence by ip or by server name, it is worked. But if we open confluence by dns name, appears error 400. From ubuntu this name resolved. 

[Vadim Kovalchuk]

We are solved the problem. Problem was because we used dns name for server with underline (confluence_new). Thank you for all answers!

[Grigory Salnikov]

Glad you've solved this :)

[Vadim Kovalchuk]

I think that it was denied by apache tomcat, but i don't know how it can check.

You can check logs located here:

[Grigory Salnikov]

Does a message appear in this log when you get "Error 400"?

[Vadim Kovalchuk]

No, I can't find any message about this error

[Grigory Salnikov]

Have you tried to access the instance by name from other devices?

Does the error remain?

[Vadim Kovalchuk]

The same error, when i try from other device

Hi!

Try to clear the cache of your browser or just try to use a different browser.

If you use Windows, you could also flush dns:

ipconfig /flushdns
