Issue with CRM in Dynamics

(0) ShareShare

Posted on by
Hi everyone,
 
I'm facing an issue with Dynamics 365 and would appreciate some help from the community.
1. Environment Details:
Application: CRM Dynamics 365 
Region: Canada
 
2. The Problem: Whenever I try to update a contact, the system shows a generic error message
 
3. Error Message / Logs:
L’opération a échoué, car nous n’avons pas pu nous connecter au serveur. Réessayez ultérieurement.
TypeError: Failed to fetch at https://content.powerapps.com/resource/uci-infra-web/scripts/app.4b3d707f31374c59214a096455a3f10a.js:4:129575 at https://content.powerapps.com/resource/uci-infra-web/scripts/app.4b3d707f31374c59214a096455a3f10a.js:4:125965 at Object.next (https://content.powerapps.com/resource/uci-infra-web/scripts/app.4b3d707f31374c59214a096455a3f10a.js:4:126070) at o (https://content.powerapps.com/resource/uci-infra-web/scripts/app.4b3d707f31374c59214a096455a3f10a.js:4:124787)
 
5. What I've tried so far:
Cleared browser cache / Tried in Incognito mode / Checked for custom plugins
 
Does anyone have any insights on what might be causing this or how to fix it?
 
Thanks in advance!

    Most likely causes (based on your case)
     
    Network / Firewall / Proxy (MOST COMMON)
    In corporate environments (especially region like Canada):
    Firewall may block:
    • *.dynamics.com
    • *.powerapps.com
    Result:
    • Save operation fails
    • UI shows generic error
    70% cases = Firewall / proxy blocking Power Platform endpoints
    Ask IT to allow:
    • *.dynamics.com
    • *.powerapps.com
    • *.azureedge.net
