typo3 fe Login does not work

Question

I have a typo3 6.2 instance running with feLogin. Until yesterday the login works perfectly, since 2pm yesterday login is not possible anymore.

There haven't been any code changes.

What could be the issues?

The redirect works fine.

Thanks in advance

Answer 1

1. Check the logs
2. Check the TYPO3 configuration for FE|loginSecurityLevel
3. Check if rsaauth is installed when using loginSecurityLevel = rsa
