I’m glad that 2.0.4.5 worked for you. Although we don’t know what you were on before, my comment about a previous problem had the below in mind (even though your symptoms were different). To further weaken my idea that 2.0.3.3 was buggy, because it came from 2.0.3.1 which came mostly from 2.0.2.0, is that the source code for 2.0.3.1 looks like it pulled in the 2.0.2.1 fix. Regardless, these issues were the suspects…
Setting password for the first time causes never ending failed request loop #2844
Login impossible after setting GUI password #3035
2.0.2.1 fix was release-noted as:
Fixed a problem with setting the initial password on the server and some change-password issues, thanks @mnaiman
Whatever the problem was, I’m glad it’s gone now, and thanks for posting what the solution was for you…
