Get your taxes done using TurboTax

I have TurboTax  Premier 2023 Desktop version and it was working till recently (4/10/2023). There were some updates recently and then it stopped working.   The error manifests with different symptoms (1) Staying in activation loop. i.e the software keeps asking login and password (2)  Turbo Tax says "You are not connected to internet" even though internet in clearly working. 

Have spent hours in trying to find resolution but no luck. This caused me to file for tax returns extension.  Hoping to do efile instead of printing and doing paper filing.  Have tried reinstalling the software. Adding firewall entry as mentioned in this thread. 

In my case the error seems to be certificate on remote server. Hope the issue will be root caused and resolved soon.  Here are the logs from
