I tried this out but the website does not come up. Is it possible to have wildcard certificates issued to mutiple domains?

dynamic_config.yml:

next-router:
   entryPoints:
     - websecure
   middlewares:
     - security-headers
   rule: Host(`proxy.domain1.com`) && !PathPrefix(`/api/v1`)
   service: next-service
   tls:
     certResolver: letsencrypt
     domains[0]:
       - main: "domain1.com"
         sans:
           - "*.domain1.com"
     domains[1]:
       - main: "domain2.com"
         sans:
           - "*.domain2.com"

A single domain works ok:

next-router:
   entryPoints:
     - websecure
   middlewares:
     - security-headers
   rule: Host(`proxy.domain1.com`) && !PathPrefix(`/api/v1`)
   service: next-service
   tls:
     certResolver: letsencrypt
     domains:
       - main: "domain1.com"
         sans:
           - "*.domain1.com"
