PgAdmin 4. Unable to work under Internet Explorer 11 and Chrome

Question

I am new to PostgreSQL and I have installed Postgresql 12 version for win64 from EDB website. After the installation I tried to use pgAdmin but I ran into some issues:

• With Internet Explorer I got this error "your browser was detected as Internet explorer 11. which is either deprecated or not supported by pgAdmin4"

• With Google Chrome I got this error. "The server could not verify that you are authorized to access the URL requested. You either supplied the wrong credentials (e.g. a bad password), or your browser doesn't understand how to supply the credentials required."

I did what many others told to do:

• Internet Explorer Enhanced Security Configuration turned off.
• changed the PgAdmin default browser to chrome.
• Added my default PgAdmin server to Internet Security Trusted list.

Please help !

Answer 1

Ran into the same issue. There is not much information about IE11 not being supported anymore. All I can see is

The following browsers are currently supported, but that support will cease in a future release of pgAdmin. It is strongly advised that a supported browser is used instead:

Internet Explorer 11

The followings are supported

Chrome 72

Firefox 65+

Edge 44+

Safari 12+

I have installed Edge and set it as the default browser. Now everything works as expected.
