Contact US page does not work

Hi Team
Please advise how i could get past this issue . When i click on Contact US page I get an error “There was an error trying to send your message. Please try again later.”

I have visited the forum and found a relevant post
https://wordpress.org/support/topic/failed-to-send-your-message-please-try-later-or-contact-the-administrator-by-an-23/

Based on this information I had also included Captcha now

But still the same error

Please let me know how to fix it
I also checked all emails and settings associated are fine
