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.
