webclient stop working

[#1]

Hi all

I would like to request your assistance  an issue with our SAP Business One Web Client running on SAP HANA, which suddenly stopped working.
I have already performed the following troubleshooting steps to identify and resolve the issue:
Checked port 443 on the firewall.
Cleared the browser cache.
Uninstalled and reinstalled the Web Client.
Stopped and restarted the Web Client service.
Stopped and restarted SAP Business One Server Tools.
Restarted the Server Tools service through Windows Services.
Despite these troubleshooting efforts, the Web Client is still not working.
Additionally, I checked the SSL certificate and found that it has expired. Please refer to the attached screenshot for your reference.
Could you please investigate the issue and advise on the necessary steps to restore the SAP Business One Web Client? Kindly verify whether the expired SSL certificate is causing the issue and assist with renewing or replacing the certificate if necessary.

any suggestion how to fix this issue is highly appreciated

Thank you
