The application server could not be contacted

Bonjour,

J'ai installé récemment un environnement PostgreSQL en version 10.3 sur plateforme Windows 10 en 64 bits.

pgadmin4 a été installé également, et j'ai pu me connecter au SGBD à partir de ce client.

A présent, il ne m'est plus possible de me connecter, car je rencontre le message indiqué dans l'objet du post :  "The application server could not be contacted", sans en connaître la raison exacte.

J'ai parcouru rapidement les différents logs que j'ai pu voir, sans trouver de message particulier lié à ce problème.

J'ai également désactivé le pare feu sans que cela résolve ce problème.

Quelqu'un pourra t'il m'éclairer sur ce type de problème ?

En espérant que cela puisse aider à la résolution du problème.

D'avance merci.

Re : The application server could not be contacted

C'est le fichier de log de pgAdmin4, et ça n'apporte aucune information sur pourquoi le serveur refuserait la connexion. Il faut plutôt trouver le log du serveur.

Merci du retour.

Il faut comprendre par là, le log du serveur postgreSQL ?

Merci pour la confirmation.

Re : The application server could not be contacted

Bonjour à tous,
Idem, j'ai installé PGADMIN 4 v3.0 sous Windows 10.
J'ai réussi à le lancer une fois faire la connexion vers mon serveur (avec Postgis) et maintenant impossible de le démarrer : The application server could not be contacted
Je me dis qu'il faut peut-être copier le fichier "pgadmin4-3.0-x86.exe.sig" mais je ne sais pas ou (et je ne trouve pas l'information sur le site de PGADMIN).
En attendant cela fonctionne avec la version PGADMIN 4 V1 mais qui ne dispose pas du français.
Avez-vous une idée ou je dois copier le fichier, ou ce que je peux faire pour utiliser la V3.0 ?
Je vous remercie
bonne journée
Laurent

Re : The application server could not be contacted

pour info, en vidant le répertoire C:\Users\user\AppData\Roaming\pgAdmin cela fonctionne à nouveau...Je test avec un redémarrage.

Re : The application server could not be contacted

malheureusement après un redémarrage il faut vider le répertoire C:\Users\user\AppData\Roaming\pgAdmin , et re-créer les connexions... pas très pratique.
Si vous avez une solution.
merci beaucoup
