Problem connecting to report server

[mohammadjavaher]

Hi.

I have published my Power BI Report Server into internet using a firewall (SOC team manages firewall). I can connect to RS from both company LAN and other internet connections (Mobile data, home WiFi, etc.):

Connecting to RS from Chrome on Android

But I cannot connect to RS using Power BI Mobile App, using the same networks and at the same time:

Connection problem to RS using PBI Mobile App

I cannot remember when this started to happen. I can't determine if the problem is from RS, firewall or Mobile App. RS is Jan. 2025 version and App is 21241759 version.

Please help.

Thanks

Hi @V-yubandi-msft 

Thanks for your reply. Sorry for being late. Results are:

I used your suggested format for RS address in mobile app. This is the result:

And also verified that /reportserver is publicly accessible (in addition to /reports which has been already checked):

Here is SSL Labs result (I don;'t know how to interprete it!):

I verified authentication types in RSReportServer.config, but couldn't find <MobileReportPortalUri> tag and where to insert it.

I will be thankful for further helps.

Hello @mohammadjavaher ,

Thanks for sharing the details and screenshots. It's good  to see that you've checked public accessibility and confirmed the SSL certificate chain. That's an important step.

However, it seems the setting is missing in your RSReportServer.config file. This setting is crucial for the Power BI Mobile App to connect to your Report Server properly.

To resolve this, add the following line inside the section of the config file.

<MobileReportPortalUri>https://yourdomain.com</MobileReportPortalUri>

After making this change, remember to restart the Power BI Report Server service to apply the update.

For more details, you can check out the official documentation:

Hope this helps.. Please Accept as solution if this meets your needs and a Kudos would be appreciated.

Thanks for your reply.

In which section of config file should I add this line?

Hi @mohammadjavaher ,

Thank you for engaging with the Microsoft Fabric Community. This issue commonly arises when making PBIRS accessible externally and using it with the Power BI Mobile App. The error often stems from specific mobile app configuration requirements ensure you do not include /reports or /reportserver in the mobile app’s server address.

Correct format:

Ensure you are using HTTPS with a publicly trusted SSL certificate and verify the entire certificate chain through SSL Labs. Self signed or internally issued certificates typically do not function well on mobile devices.

Ensure that Port 443 (HTTPS) is open, headers are not stripped, all necessary HTTP verbs are allowed, and both /reportserver and /reports are publicly accessible.  Additionally, since the mobile app supports only certain authentication types, update RSReportServer.config to enable the appropriate ones.

Ensure this setting exists in RSreportServer.config.

<MobileReportPortalUri>https://yourdomain.com</MobileReportPortalUri>

Above is a key checklist relevant to the issue you're experiencing. Please review and verify each item to help identify the root cause of the connection problem with the Power BI Mobile App.
