Any Mail gun user please help me out Thanks

Answer 1

I have been having the same issue with Laravel 4.2 and Mailgun. I have contacted MG they are blaming this error on DDoS attacks they have been having. I included this thread in my latest support ticket. If you have any useful information to help them please include it here. I have noticed that it is only happening early to mid morning daily.

Mailgun's response 5/24/2016:

We made changes with our hosting provider late this morning that looks to have resolved the issue.  Please let us know if you continue experiencing this error.

Answer 2

I'm getting the same error, but it is easy to solve and resolve for me!

Updating the version of php5-curl solved! FOR UBUNTU => sudo apt-get install --only-upgrade php5-curl

enjoy! ;)

Answer 3

I also getting the same issue. After debugging the code with try-catch what I noticed is, some of the recipient email ids have spaces like:

testmail@google mail.com instead of testmail@googlemail.com may this answer give a way to solve your issue
