nginx - SSL - CA seems not used

[4lex11s]

Hello,

Thank you for your software!

After a fresh installation, when I would like to edit a document from the example page, I received "The editor is loaded with the "The document could not be saved" message.
Looking in the logs, I encounter a self-signed certificate error although the external CA certificate is in the Data folder with the right name :
"userid":"uid-1"}]} Error: self signed certificate in certificate chain

And it's also the right CA certificat:

 pwd
       /var/www/onlyoffice/Data/certs
openssl verify -verbose -x509_strict  -CAfile ca-certificates.pem onlyoffice.crt
    onlyoffice.crt: OK
ls /var/www/onlyoffice/Data/certs
      ca-certificates.pem  dhparam.pem  onlyoffice.crt  onlyoffice.key
env
    SSL_CERTIFICATES_DIR=/var/www/onlyoffice/Data/certs

Furthermore, the used certificate is signed by only one certificate authority

Insecure Workaround
-e USE_UNAUTHORIZED_STORAGE=true

How to reproduce

extPrt=80
CtPrt=80
extPrtSSL=443
CtPrtSSL=443

domaine="docs.example.fr"
OOdata=/var/local/onlyoffice/$domaine
OODocs=/var/local/onlyoffice/$domaine/docs
OOCache=/var/local/onlyoffice/$domaine/cache

OOrepertoires=("$OOdata" "$OODocs" "$OOCache")
for i in ${OOrepertoires[@]}; do mkdir -p $i -v ;done


sudo docker run -i -t -p $extPrt:$CtPrt -p $extPrtSSL:$CtPrtSSL  --restart=always \
    -e JWT_ENABLED=false \
    -e SSL_VERIFY_CLIENT=optional  -e NODE_TLS_REJECT_UNAUTHORIZED=0 \
    -e SSL_CERTIFICATES_DIR=/var/www/onlyoffice/Data/certs  \
    --hostname $domaine \
    -v $OOdata:/var/www/onlyoffice/Data \
    -v $OODocs:/var/log/onlyoffice \
    -v $OOCache:/var/lib/onlyoffice \
    --name $domaine \
     onlyoffice/documentserver

Did this work in previous versions of DocumentServer?
no

DocumentServer Docker tag: & Host Operating System:

docker image ls
