Why can't Guzzle see the letsencrypt certificate file on the Ubuntu server?

Question

ubuntu

I work with the Centrifugo setup , I use this package for Lara .
In order to use SSL, I added the path to the certificate key in .env:

...
CENTRIFUGO_SSL_KEY=/etc/letsencrypt/live/папка_с_именем_домена/privkey.pem

but as a result, when I try to send data with a centrifuge, I get an error that there is no such file:

SSL private key not found:  /etc/letsencrypt/live/папка_с_именем_домена/privkey.pem at /var/www/web-app/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php:474)

while in tinker it returns true :

file_exists('/etc/letsencrypt/live/папка_с_именем_домена/privkey.pem')

I uploaded the file to the root of the project, in this case everything is OK

Maybe there is a workaround with the location of the certificate key file?

Does the client have access rights to the folder and file?
