Attaching a file to a Confluence page causes a session expire message

Hi,

 

I'm using Confluence 6.2.2 and when I'm trying to attach a file to a page, either in edit mode or drag and drop the attachment on the page, I will get a session expired message (See pictures below).

When I close the upload window, I don't have to login again.

Note that the time that I've been logged in does not matter.

What do I need to change to fix this?

 

Thanks,

Rudy

Hi Rudy,

To assist, can you please tail your Confluence logs, replicate the error, and send us the lines that occur when you do this?

Please also confirm your database type and version and confirm if the Server Base URL matches the URL that you use to access Confluence.

Thank you!

Kind Regards,
Shannon

Hi,

I'm a colleague of Rudy.

We have a workaround, which is disabling collaborative editing. The logs can be found here:

Hi Bert,

Thank you for confirming that! Are you able to pinpoint what time you attempted this so I can go to the location in your logs? 

Can you confirm with us if you're running any proxy or firewall? 

Thank you.

Hi Shannon,

 

Thank you for your quick response. I tried to do some things this morning (2017-08-23) between 07.30 and 9.00.

Yes, we use a proxy with SSL certificate and we used the settings at page https://confluence.atlassian.com/doc/using-apache-with-mod_proxy-173669.html

Hi Bert,

Thank you! We have a team looking into issues with Collaborative Editing so I've added the appropriate tag to this issue so they can step in and assist us.

One thing I did notice was this: 

javax.net.ssl.SSLPeerUnverifiedException: Host name 'pww.jira.philips.com' does not match the certificate subject provided by the peer (CN=www.jira.intra.lighting.com, OU=Lighting, O=Philips Lighting B.V., L=Eindhoven, ST=Noord-Brabant, C=NL)

It could prevent things from not working properly so you may want to look into that. In the meantime, we will continue to investigate via your logs.

Kind Regards,
Shannon

Hi Shannon, 

I've removed the external gadget entries which caused the javax.net.ssl.SSLPeerUnverifiedException, but that has no effect on the problem. Do you have already any insight in what causes the upload problem?

Rudy

Thanks Rudy! I was just letting you know about that since when certs don't match the URL it does cause other problems so I wanted to make sure you were aware of that.

We've properly tagged the issue now so the team handling the Synchrony issues will be able to have a look at this.

Thank you!

Kind Regards,
Shannon

Hi guys, I have same issue with Confluence. Upload of image or other file report same error:
"Your session has expired. You may need to re-submit the form or reload the page."
But when I try to insert/upload image on page comment, that works ok.

My version:  6.1.2

We just upgraded to 6.4.3 and we are seeing issues. If we edit a page and try to add a file we get the error. If we "Drag and drop to upload or browse for files" that attaches the files without error. Any update on this?

For now, we've surrendered. We've disabled collaborative editing. It has probably to do with proxy configurations. 

After I update to 6.3.3 it was solved. So, good to know that new version is not good again :(

Hello, guys.

 

This problem is usually caused by a bug in Synchrony, which we can check below:

 

I personally recommend the third workaround of renaming the session cookie and restarting Confluence to fix this issue.

 

Best regards,

I ran into a similar problem, however; my issue was caused by an external proxy that didn't support session persistence (due to a config problem).

This was an F5 LTM.  On the LTM I had to configure the virtualserver's "Default Persistence Profile" to "cookie" which causes the F5 to insert its own cookie into the HTTP header that tracks which node was in use for that session.

Mea culpa, didn't heed the warning in Atlassian's documentation which states, "Use a load balancer with session affinity and..."

Adding here for any others that encountered the same mistake, but aren't affected by the bug referenced in @Bernardo Andreeti's comment.
