Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.1.2 Build 20230210 Rel.62992

Hi,

 

I'm trying to manually upgrade an ER605 V2.0 from the router's web portal from 2.1.2 Build 20230210 Rel.62992 to ER605(UN)_V2_2.2.5 Build 20240522 but I'm getting this error "Upgrade Failed. Please check the upgrade file and try again."

 

Router HTTPS is enabled is can be seen in the below screenshot

 

Any ideas what could be the issue ?

UPDATE: 

I just noticed the note on the previous version: 

Please make sure the firmware version before upgrading is ER605(UN)_V2_2.2.3 Build 20231201, otherwise the firmware upgrade will fail.
 

After upgrading to 2.2.3, the update worked.
