Currently I'm having the below error, I'm struggling to figure out what has gone on with this as it has been previously working without issues. I've been leaving my Traefik to update as normal, now I'm having the below issue which I can't seem to resolve.

"Error renewing certificate from LE: {mydomain..com [\*.mydomain..com]}, error: one or more domains had a problem:\n[_mydomain..com] [_.mydomain..com] acme: error presenting token: cloudflare: failed to find zone mydomain..com.: ListZonesContext command failed: error from makeRequest: HTTP status 400: content "{\"success\":false,\"errors\":[{\"code\":6003,\"message\":\"Invalid request headers\",\"error\_chain\":[{\"code\":6103,\"message\":\"Invalid format for X-Auth-Key header\"}]}],\"messages\":[],\"result\":null}"\n[mydomain..com] [mydomain..com] acme: error presenting token: cloudflare: failed to find zone mydomain..com.: ListZonesContext command failed: error from makeRequest: HTTP status 400: content "{\"success\":false,\"errors\":[{\"code\":6003,\"message\":\"Invalid request headers\",\"error\_chain\":[{\"code\":6103,\"message\":\"Invalid format for X-Auth-Key header\"}]}],\"messages\":[],\"result\":null}"\n" providerName=dns-cloudflare.acme

Any assistance on this would be much appreciated! Thank you.

I had to put multiple full stops into the [mydomain.com](http://mydomain.com) sections as new users can't have more than four links in a message 🙂

Looks like wrong Cloudflare credentials.
