Hi @Nordbahnkurti > [@Nordbahnkurti](#): > > I ran this command: the error message is unclear. What's the page before? Looks like you didn't define a certificate name. ---

Jürgen, thanks for the quick reply! The website was previously installed on another server. Lets Encrypt could not be installed there because the webspace and domain had different addresses according to the company. (See attached error message!) The company has now given us a new web space and we have transferred the data there. Now we wanted to install Lets Encrypt again via Plesk and it doesn’t work again! What could be the cause? Maybe we made too many attempts to install Lets Encrypt on the old webspace? I dont know! Jürgen, maybe you can help us and excuse my bad english! Best regards from Austria Hofer Kurt ![Screenshot_2020-03-30.jpg](https://global.discourse-cdn.com/letsencrypt/original/3X/1/0/1098369de8cc972f3853699b5c4bd87533c6d270.jpeg) ---

What could be > the cause? That's a configuration error of your webspace. Your provider must fix that. Or remove that domain name ws111\*. `fischereiverein-marchegg.com` has that ip - 138.201.139.33 - so that looks correct. Yep: > D:\temp\>nslookup [ws111468.mbmwebhost.net](http://ws111468.mbmwebhost.net). > > Name: [ws111468.mbmwebhost.net](http://ws111468.mbmwebhost.net) > Address: 138.201.161.149 That's another ip address, that can't work using http validation -\> configuration error of that domain name `ws111468.mbmwebhost.net`. That's the job of your hoster to fix that, it's their domain name. ---
