• Check aveksaServer.log for related errors; the problem might be due to a certificate trusted earlier through the UI (Admin > User Interface > Files > SSL Certificates) that may have recently expired. If confirmed that an expired certificates exists (check on the UI > Admin > User Interface > Files > SSL Certificates), the next steps would be to delete the expired cert(s) through the UI, optionally trust/upload the new certs for those endpoints, then try generating/downloading AFX client certificate.
