"Invalid URI: The hostname could not be parsed"

[rogletree]

Encountering an error message when I tried to use Power BI Desktop this morning. I open a file, and I get this:

Normally when I open a file it has me already signed in, but for some reason I'm not able to now.

I've tried just restarting my computer, reinstalling Power BI Desktop. If anyone has any ideas how to fix this, that would be great.

It did give me this other information about the error:

Error Message:

Hi, @rogletree  most of the case in corporate environment we can see the problem. 

Lets Fix the Registry for Proxy Authentication

Steps:

1. Press Win + R, type regedit, press Enter
2. Navigate to one of these locations:
   • 64-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Power BI
   • 32-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Microsoft Power BI Desktop
3. Create a new REG_DWORD entry with the name: UseDefaultCredentialsForProxy 
4. Set the value to 1
5. Restart your computer for changes to take effect

Thank you for the suggestion but unfortunately this did not work. Still having the exact problem and same error message even after adding the new line in the registry editor.

Hi @rogletree,

Thank you  for reaching out to the Microsoft fabric community forum.
The error “Invalid URI: The hostname could not be parsed” usually means that Power BI or the system is not able to read the URL or hostname properly. This mostly happens due to incorrect format in the link, or network and proxy issues.

Here are some common reasons and what you can check:
Wrong Format in Hostname or URL there might be extra spaces, special characters, or backslashes \ instead of forward slashes / in the link. Please check carefully if the link or proxy address is written correctly.

DNS or Network Issue sometimes, the system can’t convert the hostname into IP due to DNS problems. Also, company firewalls or proxies can block certain links. Please check with your IT team to make sure there are no network blocks and the proxy settings are valid and  If the issue is happening only in Power BI, check if any URL or data source settings inside the file are incorrect. If possible, try opening a different PBIX file to see if the same issue comes.

User or Machine Specific Issue if this error is not happening for others, it might be related to your system's settings or permissions. Try running Power BI as administrator or using another network to test.

Hope this helps if you have any queries we are  happy to assist you further.
