SSL_PROTOCOL_ERROR square domain

StaceyBurt — Sun, 21 Sep 2025 07:40:04 GMT

I am often receiving an error when accessing my square domain site, usually when clicking via a link. Error reads:

This site can’t provide a secure connection

ERR_SSL_PROTOCOL_ERROR

is this due to something I have done when setting up my site? Or is it a square error? Help please, I am losing online sales!

Hi @StaceyBurt ,

I think you may be referring to square online? It takes a few hours for the SSL certificate to be created, then the warning will go away. It does require that all the DNS changes have been done correctly.

Are you able to provide the domain in question ?

Regards,

Bruce

Hi,

I don't have a personal domain, I have a free Square domain. When I looked into this problem on the community site the problem seemed to be with other people loading paid domain names, which I don't have, so I don't know how these DNS and SSL certificates work.

It's www.staceyburtcreative.square.site

Hi there @StaceyBurt,

Thanks for reaching out to us to raise this with us and sorry to hear you're running into these issues.

I've just taken a peek at your link on my end and I'm also returning the same error message, however, it looks like you have created another site before this one which is working and loading as expected. See here: https://staceyburtcreative.square.site/

I'm suspecting that the issue here is that a duplicate site has been created in error. When you navigate to your Square Online Overview page, in the top-left corner you will see a dropdown menu where you can check to see whether multiple sites have been created. I've included some screenshot references below of what this will look like.

Can you check this on your end and let me know if you can see the two sites listed here?

I'll keep a lookout for your reply!

Hi thanks for looking at this for me.

I do have two sites, one is unpublished and I actually deleted it yesterday, but it's not disappeared. Anyway, this issue was happening long before I added the second site.

Thanks for taking a look at this, @StaceyBurt.

The other thing we can get you to check is to ensure that you have synced your Square Online sites to a physical location. Square Online is unable to sync to a mobile location, so if you have recently changed one or both of your Locations to a mobile location type, this will impact your live site.

If you have made no changes to your Square Account Locations and you have removed any duplicate sites, I suggest reaching out to our Support Team directly so that a Square Online specialist can take a look at your settings in greater detail with you.

You can call support on 1800 760 137 (Mon - Fri, 9 am - 5 pm Melbourne time), or contact us via online chat or email. See the below steps.

1. Sign in to your Square account

2. Head to our contact page https://squ.re/3AWfZs2

3. Go to "Other", then "I don't see my issue"

4. Click "Message us", "Email us" or "Call Us"

Or, if you see the new chatbot help flow, type “support” to bring up a list of contact methods.

Yes my location was set to mobile, I'm thinking this was the issue. I don't fully understand this, but hopefully it's fixed now!

I greatly appreciate your assistance.

Stacey

I'm glad this helped to identify the issue and get you back up and running, @StaceyBurt! 😊

Locations can be one of those fiddly settings I'm afraid, but this Support Article includes some great tips for troubleshooting display issues with Square Online.

To quote the article for quick reference, Square Online doesn’t sync item stock from mobile locations, so items only available at a mobile location will be marked as Unavailable in Square Online.

Don't hesitate to reach back out to us with any further questions.
