I am encountering an internal server error when using the online query interface

Question

When I open the xmatch page or try to make an ADQL query in the Datalab Query interface, I am shown this error. Is there a way to fix it and is there anything I have done to cause it? I'm not sure of the exact time of the first time I encountered the error but it has been like this for about a month at least.

INTERNAL SERVER ERROR

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Thank you for bringing this to our attention. This is likely an old session creating problems and doesn't appear to be caused by anything you have done. We will look into the issue further but in the meantime you should be able to get around it by logging out of the Data Lab system (click the Logout link at the top of the page) and then logging back in (click the login link at the top of the page).

Let us know if this resolves the issue for you!

Thank you. When I press log out, I seem to remain logged in, which is why it seems that I am unable to leave the old session even if I thought I logged out. I tried logging in with a different web browser on the same computer and this solves the issue. I expect that if I cleared the browser cache this would also solve the issue.

Can you give the logout sequence another try and see if it works for you now? We have applied a change that should help.

If it still doesn't work, as you mentioned you can clear the data in your browser for the Data Lab site and then things should be back to normal. Sorry for the inconvenience!

Yes, it worked this time. Thank you!
