python instruction smtplib.SMTP("smtp.office365.com", 587) does not return on linux azure VM

Question

Hello

I wrote python a script to send an email from an @harsh.com .com email address.

the script works correctly on my windows pc, and on my local virutal linux macchine.
but when i run the same script on linux VM in Azure, the command smtplib.SMTP("smtp.office365.com", 587) never returns.
this is a screenshot of the traceback when I interept the script

Could you please help me to fix this issue?
Thank you.
