Hi EGHANA After checking the logs it is showing below error: sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) duplicate column name: connect_timeout [SQL: ALTER TABLE server ADD COLUMN connect_timeout INTEGER DEFAULT 0]
It seems that problem with the database file when you did upgrade/downgrade the PostgreSQL.

You may find the file at "*C:\Users\<user_name>\.pgadmin*" folder. - Restart the pgAdmin4 On Fri, Aug 28, 2020 at 2:32 PM EGHANA MARREDDY <180050...@kluniversity.in> wrote: > Hi Akshay, > > Thanks for reaching out! > > Here are the log files as advised. > > Thanks, > Meghana > ------------------------------ > *From:* Akshay Joshi <akshay.jo...@enterprisedb.com> > *Sent:* 28 August 2020 09:04 > *To:* EGHANA MARREDDY <180050...@kluniversity.in> > *Cc:* pgadmin-supp...@postgresql.org <pgadmin-supp...@postgresql.org> > *Subject:* Re: URGENT ACTION : Fatal Error with launching pgAdmn > > Hi EGHANA > > Can you please provide the pgAdmin4 log file available at " > *C:\Users\<user_name>\AppData\Local*" folder. > > On Thu, Aug 27, 2020 at 7:54 PM EGHANA MARREDDY <180050...@kluniversity.in> > wrote: > > Hi Team, > > I am facing issues with launching the pgAdmn 4 from Postgresql 12.
