The SMTP mail activity gets stuck without timing out

Hi guys, I have a strange problem for some reason, SMTP mail activity stopped working. I did everything I could, like updating the activity … among others I saw in the forums, but nothing worked. Also, I found that when all processes related to UIpath such as assistant services are killed and later run the activity works again I have no idea what is happening, and I am scared because this problem is intermittent and I have no real solution for this problem.
I hope you can help me

I’ve had this a few times, over the last few years, rebooting my machine fixes it.
Alternatively you could use the Send Exchange Mail activity for sending emails instead which doesn’t seem to exhibit this problem.
