Failed connect to - Connection refused

Dear support!


I integrated my web application with Trello's REST API.


I used the following method: '{yourKey}&token={yourToken}', that I putted my key and token.


In sometime, it works, after three ou four requests, the Trello's REST API starts to return to my application 'Connection refused' like this: Failed connect to"; Connection refused.


I appreciate anything that can help me in that problem.


Thank you in advance!

@Anderson Souza Are you getting a 429 HTTP error code indicating a rate limit problem?

Thank you for response, @Iain Dooley!

No. Only the following messages:


Connection refused 

Failed connect to; Connection refused"

I believe that requests did not arrive in the Trello application. The server is blocked.

I appreciate any information that help me.

I meant: "The server can be blocking my requests"

@Anderson Souza Hmm I can confirm that I can run:

telnet 443

from where I am, can you do the same?

I can't. See the following message:

"telnet 443


telnet: connect to address Connection refused"

@Anderson Souza Hmm okay well can you send this info to the support team? You just go to and jump through all the various automated hoops until you get to the real contact form.

Thank you, @Iain Dooley.

Before here, I had sent to support team, but I was instructed post here.

Yes, I will send the message there again.

Iain Dooley Community Leader Jun 16, 2020

@Anderson Souza I'll ping the team in Slack too, sorry for the runaround.

Nothing! I appreciate the support.

I sent the message in support too.

@Anderson Souza hey I heard back from one of the community support team via Slack, he mentioned this as a potentially better place to ask the question, @bentley  answers questions frequently on this forum:

Thank you, @Iain Dooley 

I will send my question there too.
