Use Edocman cannot upgrade new version Joomla

Hi Team,

While updating Joomla 3.9.8 to new version 3.9.12 (current version), I cannot upgrade because error facing below: "Invalid login".
I tried multiple times but not successful.
Please help me fix the problem
Thank you very much!

Hi,
There aren't any relation between Edocman extension and Joomla Update. So that, we can't help you to solve this kind of issue. By the way, you can download Joomla Update Package from Joomla site and upload it into your hosting before extracting it. That's one way to upgrade Joomla system.
Thanks
