[SOLVED] Server resintall - Can't provision TLS (Missing file)

Hi,
I totally reinstalled the server (rebuilt the VPS) and I’m getting this error when trying to provision the TLS certificate:

Something unexpected went wrong: [NeedToInstallFile(’[MYDOMAIN]/.well-known/acme-challenge/CyYGsNLprIZz1–MxZKuunr0VVwdVy4KABz3nfD9NIM’, ‘CyYGsNLprIZz1–MxZKuunr0VVwdVy4KABz3nfD9NIM.1KaQ2v4XbH5FcOOWmOMKBF92fbEfX9tmsoU_g41iPIo’, ‘CyYGsNLprIZz1–MxZKuunr0VVwdVy4KABz3nfD9NIM’)]

Here is what the log says:

Log:

It was only temporary it seems. This is now fixed.
