suddenly stopped the REST authentication (/rest/auth/1/session)

[Shunmuganathan M]

Rest API was working fine.  Suddenly it stopped.

(/rest/auth/1/session)

It is always getting the following error, But the user name and password are correct.

{
"errorMessages": ["Login failed"],
"errors": {}
}

What will be the issue. It is already in the production.

Can you help me?

[Tomas Gustavsson]

I guess some certificate have timed out, if you use https or certificate for AD ?

[Shunmuganathan M]

In the localhost also getting same issue

[Tomas Gustavsson]

Can you use the Rest API account to login on jira? have the password timed out? 

[Shunmuganathan M]

Yes, same user id and password is working fine in main jira boad.

[Tomas Gustavsson]

Can you try to catch more info around the login failure, with either with a try catch statement och if there already is some more info in any log file.

Have you changed any thing since last time when it actually worked? 

Need more info, to be able to figure this out. 

[Shunmuganathan M]

Nothing was changed. It was worked for last one month. It was stopped working from yesterday.

Now I am getting following error message for all the users.

{
"errorMessages": ["Login failed"],
"errors": {}
}

[Tomas Gustavsson]

If no one is able to login, this could happen if you are out of disk space,  if you have access to the server, then you can delete some old log files.

[Shunmuganathan M]

It is cloud account, How can we delete old logs?

[Shunmuganathan M]

Thanks for your support. I found the issue. Actually they stopped the cookie based authentication. Now I am using another type of authentication
