Q: Detailed Description of the Problem
A: So I’ve created a new site and decided to check which information is displayed in Site Health report.
I see these 2 critical errors:
And this recommended improvement:
None of these issues present when I use some other (non-docker based) solutions to create sites locally (OSPanel.io, for example).
Thank you for reporting this. I do see those messages on my end too. We’ll take a look at this!
I have exact the same Problem
In my case it will connect to port 80
Excited to use devKinsta but unfortunately, I couldn’t not run any cron which is very important to my project.
Please see the following:
Error: cURL error 7: Failed to connect to website.local port 443: Connection refused (http_request_failed)
Same thing when I’m not using SSL
Same error when using normal PHP Curl
Tools > Site Health > Could not complete a loopback request
I’ve disabled windows defender but didn’t fixed the issue.
Everything is fine when I’m using localwp.
Thanks!
Sorry for the wait here, @josephg . I’m checking with our developers on this and will get back to you shortly.
Wordpress site health is also giving me:
"“The REST API request failed due to an error.
Error: cURL error 7: Failed to connect to butterfly.local port 443: Connection refused (http_request_failed)”
What does it mean and how do I fix it?
I’m also getting this related error:
"Loopback requests are used to run scheduled events, and are also used by the built-in editors for themes and plugins to verify code stability.
The loopback request to your site failed, this means features relying on them are not currently working as expected.
Error: cURL error 7: Failed to connect to butterfly.local port 443: Connection refused (http_request_failed)"
Hi @michael ,
Is there any perspective as to when this update is going to be released?
I’m running into the same problem for multiple projects I’m working on.
Really liking DevKinsta so far, but this has been the only big downside for me.
Hi @Bob_van_de_Leur 
I’ve confirmed we do still have this listed on our side to be addressed, however I don’t have any type of ETA available, apologies. I understand the need to have that functioning properly and will certainly bump it with our development team. Hopefully we will have more news for you on that soon 
Same here and its really pushes us to go back to MAMP…sad 
This issue “The REST API encountered an error…local port 443… your site coulnd not complete a loopback request” is still popping in my localhost’s wordpress site health.
I seek an update please…
I’m afraid no updates as of yet but I’ll be sure to post here as soon as we have more information on this.
This (see quote below) is still very much a part of my every day reality. I seek an update. Please advise…
"The REST API is one way WordPress, and other applications, communicate with the server. One example is the block editor screen, which relies on this to display, and save, your posts and pages.

Hi @kadso - I’m afraid at this time we don’t have an update to share yet on this issue. Thank you again for your patience on this.
Thank you Michael.
Anyone care to weigh in here an guide this non-programer where to look to find others where sooner rather than later timing is the working premise?
Hi Michael,
I’m still getting the two error messages below. What is the latest on resolving this topic?
