Did you make sure to remove the local data in both locations?
C:\Users\<user>\AppData\Local\Postman and
C:\Users\<user>\AppData\Roaming\Postman

If this doesn’t work would you please try disabling your GPU?

If none of the above options work, please send us your logs so we can investigate further at help@getpostman.com and please refer to this thread.

Basically the first program with these stupid open issues. You can download a better written program from indian malware sites. Shame

The app did not open, however no error was thrown.
This is my first time using Postman, and I could very well be misusing the application.
However, I expect that opening an app… should open the app.

Here are the logs from the main.log file,

    [14911][1602036836785][main][info]["Booting PostmanAgent 0.2.1, darwin-19.6.0 on x64"]
    [14911][1602036836789][main][warn]["Postman Agent~Main~populateInstallationId: Failed to get installationId from agentSettings but with no error"]

    [14911][1602036837554][main][info]["AutoLaunch: isAutoLaunchDefaultBehaviourSet is set and persisted."]
    [14911][1602036940519][main][info]["Quitting app"]

My settings.json:

{"installationId":"66ea4470-4d2f-4bec-b3aa-e430701f8edb","downloadedVersion":null,"isAutoLaunchDefaultBehaviourSet":true}

This is only a minor inconvenience because I will be using the website builder (until I am forced to revisit this issue due to browser limitations).
If I do find a resolution I will be sure to post here.

Hey @_Octal :wave:

Those logs indicate it’s from the Postman Agent, it’s a helper app to enable sending of requests using the Postman web app - Once you have the web-app open, select the “Desktop Agent” to send the request using the Postman Agent (Make sure it’s running).

Alternatively, download the Postman native app from here: Download Postman | Get Started for Free :+1:

I have been using postman on my PC for quite sometime in my org, but it stopped working all of a sudden. I just get a blank orange screen when I try to launch postman. I dont remember doing any changes on to my PC. I tried deleting the local copies and also uninstalling and reinstalling the softwares but still facing the same issue.

Pls find below the logs from the log file. Appreciate if anyone can help me to resolve the issue. I have attached the screenshot as well.

Could you try disabling GPU as mentioned in the comment above and see if that helps? Article link below:

Hi,

Thanks for your response.

I tried this just after posting the message and it actually resolved the issue, but I am wondering why did this issue occur in the first place when I did not change anything in my PC.

Thanks
Kishore

ive had the same problem all day today and i second Kishore2b’s question

used postman for 1.5 hours this morning, all fine. i closed it and then came back an hour later and it just wouldnt open.

same error, same blank loading animation and same logs as [kishore2b] above.

Error encountered while creating root CA
Could not find openssl on your system on this path: openssl

Error generating rootCA certificate for HTTPS proxy
Could not find openssl on your system on this path: openssl

i couldnt find any reports or help on this at all until i stumbled on to this thread by pure and absolute luck. Disabling the GPU as suggested fixed the issue.

Im not posting to say it fixed it though, i want to understand how in the space of an hour this software decided im just not working ever again, and the only help im giving you is to say OPEN SSL is broken (which is nowhere near the actual issue)

ive lost an entire business day to this and its super frustrating, especially on something that is usually so reliable.

35

Thank You! I also faced same issue and resolved after GPU true on Environments Variable.

36

It helped. Thank You!.

37

It works! For any upcoming upgrades should we keep this flag set to true?
Thank you!
