Hi Jessica,

 

I am sorry to hear you are having teething troubles with pgAdmin4. I have 
become quite an enthusiastic user of the package (it took a while!). I am using 
thing the following (from the Help/About menu):

 

Version

2.0

Copyright

Copyright 2013 - 2017, The pgAdmin Development Team

Python Version

2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:42:59) [MSC v.1500 32 bit (Intel)]

Flask Version

0.12.2

Application Mode

Desktop

Current User

pgadm...@pgadmin.org

 

This works just fine, and yes it does connect to the three servers I have 
locally and remotely. The things I like about this version is that it loads in 
quite a reasonable time now, but most importantly it is stable. 

 

pgAdmin3 had more bells and whistles, but it never, never, never was stable 
enough for me to have confidence in it. It would certainly crash in Windows 10 
every hour or so – which was so annoying. If pgAdmin4 crashes at all, it’s only 
once a week, which puts it in the random noise category.

 

The questions Neel asked are vital – if you have any concerns, uninstall your 
pgAdmin version and try again.

 

I’ve moved onto postgres 10.0 also and that transition seemed pretty seemless.

 

Cheers

 

Nigel

Subject: Re: The application server could not be contacted Error

 

I am on Windows 10. I have clicked through the error message numerous times and 
re-launched pgAdmin to only get the same message: "The application server could 
not be contacted". I have even left my computer running for hours to get the 
same message as well.

I’ve experienced this on two Windows machines — one Windows 7 and the other 
Windows 10. In both cases, if I click through the error message and then re-try 
launching pgAdmin it will open successfully.

 

I’ve also noticed that if I attempt to start pgAdmin too soon after booting the 
machine (and these are both older, slower machines that take a while to boot), 
then I will get this error. If I let them sit for a bit and do whatever it is 
that Windows does after booting (seems like a ton of disk activity, maybe some 
indexing), then pgAdmin is more likely to launch successfully.

I downloaded the installer of PostgresSQL version 10 and pgAdmin4 came with it, 
so I'm not sure of the version of pgAdmin4 I am using. 

This is the link I used to download the installer: PostgreSQL: Windows 
installers <https://www.postgresql.org/download/windows/> 

 

Yahoo would not allow me to attach the pgAdmin4.log because it is empty.

Hi,

 

This error will occurred only when python server is not started properly and 
application try to contact the python server but it fails. It may be due to 
some error at python backend side or python server taking more time to up.

 

Can you please provide below information ?

*       Which version of pgAdmin4 are you using ? 
*       Which version of Postgres installers and from where you have downloaded 
the installers ?
*       Can you please share pgAdmin4.log file ?

 

Thanks,

Neel Patel

I was trying to use pgAdmin4 to connect to a database, but I get "The

numerous times, as well using other solutions that were available online, and 
nothing seems to work. I was hoping you could provide me some assistance to 
fixing this issue.

 

Thank you,
