Remedy
Red Hat Quay 3.0 uses Nginx 1.12 from Red Hat Software Collections. It will be updated once a fixed is released for Software Collections. In the meantime users of Quay can disable http/2 support in Nginx by following these instructions: 1. Copy the Nginx configuration from the quay container to the host $ docker cp 3aadf1421ba3:/quay-registry/conf/nginx/ /mnt/quay/nginx 2. Edit the Nginx configuration, removing http/2 support $ sed -i 's/http2 //g' /mnt/quay/nginx/nginx.conf 3. Restart Nginx with the new configuration mounted into the container, eg: $ docker run --restart=always -p 443:8443 -p 80:8080 --sysctl net.core.somaxconn=4096 -v /mnt/quay/config:/conf/stack:Z -v /mnt/quay/storage:/datastorage -v /mnt/quay/nginx:/quay-registry/config/nginx:Z -d quay.io/redhat/quay:v3.0.3
