I have the following issue with Zabbix:
I installed the Zabbix virtual appliance, created new users (Admin, sebix). Everything worked fine for two weeks, and I could log in, add hosts, monitor, etc. The issue is as follows: Yesterday, I added 10 switches via SNMP to Zabbix monitoring. This morning, I opened the browser and found myself logged out. I tried logging in several times with the Admin user, but I got an error saying that the password was incorrect or the account was locked.
I checked the "admin" user and noticed there were failed login attempts, and the values of attempt_clock and attempt_failed were changed. I thought that maybe I entered the wrong password and locked the account so I ran the following commands:
SET attempt_failed = 0
SET attempt_clock = 0
After that, the attempt_failed and attempt_clock values were reset to 0.
I tried logging in again, but still couldn’t log in. Just to be sure, I changed the password for the Admin user, but it didn’t help, and I still received the same message user and password were 100% valid.
I also checked the roleID, and it was correctly set to 3. I created a new user "seba" with roleID = 3, and SQL shows that such a user exists, but I still cannot log in to the Zabbix web interface with this new user.
I’ve tried several options:
-Using incognito mode in the browser
-Clearing sessions in SQL
-Granting database privileges
-Restarting Zabbix
-Checking Zabbix logs (there were only 6 lines, and they were related to SNMP for one host)
In the meantime, I remembered that I have another admin user, "sebix". I logged in successfully using that account, but the problem was with 2FA, as I no longer have access to the phone with the 2FA. Consequently, I couldn’t log in. What’s strange is that after several Zabbix restarts, when I tried to log in again with the "sebix" login, I received the same error message as with the "Admin" user, stating that the password was incorrect or the account was locked is strange becouse 5min ago i can successfully login with this credentials...
I really have no idea what could be wrong, and I don’t want to reinstall Zabbix from zero since I’ve already added all my hosts for monitoring.
I would greatly appreciate any help or suggestions.
