We're hosting a web app in App Runner. Since this morning, when we try to view the site we get a certificate error:
ERR_CERT_COMMON_NAME_INVALID
I've checked the Custom Domain and DNS configuration and it all looks unchanged/correct.
I tried redeploying the service (by clicking the 'Deploy' button in AWS Console) - just in case that fixed the issue. The deployment starts but then rolls-back.
Any ideas what's going wrong?
