Hi,
I am little puzzled… since I changed my password the login into myopenhab.org does not work and any try to reset the password via “forgotten” fails with the message above ?!?!?
After some retries:
I can successfully reset the password to a new on. The message: “New password has been successfully set” comes up. But using the new pwd for a login prompts the message: “Unknown user or incorrect password”
What am I doing wrong ?

… after some painful hours I could reset the password to the new one.
Like from other posts:
uninstall openhab cloud connector
rm /var/lib/openhab2/uuid
systemctl stop openhab2
openhab-cli clean-cache
…
now I did the reset - with lots of time for the tools to sync
…
systemctl stop openhab2
installed cloud connector
… maybe something was obsolete … but after 2 days of “doing my very best” it worked out 
Maybe others run into similar…
same problem on my side 
oh no, do I really have to go throught this proceedure?
There should be a better solution, it’s just about my password on myopenhab
Regards!
