I have been running Openfire 3.6.3 and the IM Gateway Plugin 1.2.4d for about 9 months on my production server and yesterday out of no where I started receiving **Alert from Yahoo: Failed to log into Yahoo! messenger account. (unknown error) **messages for all users that have a Yahoo registration. When looking at the registrations on the Openfire server all of the Yahoo registrations sho the Last Logon Status as “never”. I have searched repeatedly in the community for some direction with this issue - but nothing. I am hoping that someone may have seen this issues before or that somone might be able to give me some direction with tracking down what is causing the problem. I have turned on debuggin on the Openfire server and reviewd the error, warning and info logs, but I am not seeing anything in the logs. Any help would greatly be appriciated.
