Certificate error

We are a corporate club. When trying to access club website on company computer, get message “Access to this page is blocked. Certificate verification error: unable to verify the first certificate.” Tried with both Microsoft Edge and Chrome. Yesterday a member tried from his home on his personal computer and got message that connection was not private, its security expired in the last day. Seems to be a certificate issue. Please advise. Club number is 4992

Yes, Club 8159 True Blue checking in here, we are getting the certificate error as well still. We can get to the site if we click through "advanced" and continue anyway, but that is not a good solution. This happened last year as well. 

Both sites are working correctly.

Some certificates have been updated recently. You might need to clear your browser cache to get the new version.

Confirmed site is working and issue can be closed. Just in case this may affect other corporate clubs, I will add the following information. After the site was fixed, several users still could not access the site on corporate laptops. Resetting cache on browsers (Edge or Chrome) did not have an effect. However, others could access the site on corporate laptops. Turns out the lack of access only affected members who had accessed the site when the certificates were not valid. Finally had to contact corporate IT, who must have reset something in the corporate infrastructure.
