I can send gmail manually, but I cannot always send SMTP gmail successfully, and the error occurrence rate is about 70 percent.
Error message : A connection attempted failed because the connected party did not properly respond after a period of time…
I have tried every method posted on the forum but still not working, such as modifying google and gmail settings,ssl,change 465 to 587 port etc.Then, I tried to put send SMTP with try catch in a loop, loop stops when it sends. Although it finally send SMTP mail, time wasted a lot in the loop. I tried to modify timeout to several seconds, but it still toke over 20 seconds to failure.
Do you have any good ideas? Thanks in advance, sorry for my mediocre English.
This is due to the server may be down or running slow. The major issue ofcourse , will be the any proxy or anti virus blocking the smtp servers blocking the connection.
And check if you have enabled the less secure apps in your gmail account
@gareth_Hua Thank you for highlighting this issue. I have been facing the same issue for some time now. If I have 100 transactions, it works for upto 60 to 65 transactions and then starts showing the error that u have mentioned. Kindly update if you have found any better approach to handle this behaviour.
Thanks,
As far as I know, it was just with the time taken by the SMTP to send the mail. I guess the short delay between sending the mails will help here. Please try providing the delay of 2 seconds between each mail trigger @Manjunath_Ramappa
