Could not Activate/Re-activate. Could not connect to internet. Error Code 90 (Tally.Developer 9)
While activating/re-activating the license, Tally.Developer 9 is displaying the following error message: Could not Activate/Re-activate. Could not connect to internet. Error Code 90.
This error may occur when Tally.Developer 9 is unable to communicate with internet. This could be due to any one of the reasons mentioned below:
● The Proxy Server settings are not configured in Tally.Developer 9
● Internet access by Tally.Developer 9 is blocked by the local firewall installed on your computers
● Total Protection software such as McAfee Total protection has the inbuilt Firewall/Network Access protection settings that prevent Tally.Developer 9 from accessing Internet.
● Corrupted Network Drivers.
● Configure the proxy server settings in Tally.Developer 9.
● Include tallydeveloper.exe, TallyAdmin.exe and TallyLicserver.exe in the exclusion list and give full access to the files. Similarly, you need to include the same file and give full access in Total protection software also (for reason 2 & 3).
● Re-install the Network Drivers.
