Accès à Hub Business

Bonjour.

Depuis la mise à jour de RDM, nous rencontrons un problème avec la validation de la Gateway configurée dans le Hub Business.
On rencontre l'erreur quand on clique sur le bouton "Check Health" lorsqu'on a choisi la gateway.
Cela ne fonctionne pas avec l'affichage d'un message d'erreur.

Voici le détail de l'erreur rencontrée :
MissingMethodException - Method not found: 'RestSharp.RestRequest RestSharp.RestRequestExtensions.AddFile(RestSharp.RestRequest, System.String, Byte[], System.String, System.String, RestSharp.FileParameterOptions)'.

Par ailleurs, j'ai configuré un second serveur sur lequel j'ai installé une gateway. Elle est en place dans la console Hub Business mais elle ne fonctionne pas. J'ai aussi un message d'erreur à l'ouverture d'une session quelconque :

Le détail de l'erreur est le suivant :
at Devolutions.Hub.Clients.HubClient.PutGatewaySessionAsync(Guid gatewayId, Guid sessionId, GatewaySession gatewaySession, CancellationToken cancellationToken)
at Devolutions.Hub.Clients.HubClient.<>c__DisplayClass172_0.<<PutGatewaySession>b__0>d.MoveNext()
--- End of stack trace from previous location ---
at Devolutions.Hub.Clients.HubClient.PutGatewaySession(Guid gatewayId, Guid sessionId, GatewaySession gatewaySession)

at Devolutions.RemoteDesktopManager.Business.DataSources.HubDevolutionsGatewaySubDataSource.GenerateToken(Connection connection, String alternateHost)

Pouvez-vous me dire ce qui ne va pas dans la configuration des Gateway en place?

D'avance, merci pour votre retour.
Cordialement,
