Unable to connect with CRA server


Recommended Posts

I cannot connect to the CRA server through ufile netfile.  It simply says 'error connecting to CRA server'.  But when installing Ufile 2021 in the first place, it came up with an istallation error '1612'.  So I suspect that this installation error is prohibitting UFile 2021 from connecting to the CRA Server to download the tax files.  Does anyone have any experience with this issue?

Me too. I am having the same issue, tried several days in a row now.  Could someone from Ufile provide help on this topic? What should be done?

I am developer; I did a test on a clean Windows 10 virtual machine, and it worked fine. So it IS a problem in uFile software - it cannot handle settings in my laptop, but it works fine on the VM.

What's special in my laptop? Nothing. I have tried everything I can think of, but it just didn't work. uFile never executed the browser successfully because I never saw the browser UI.

What I have tried:

1. make sure my Windows 10 Pro has the latest update, ufile has the latest update.

2. Edge is working properly

3. Set Edge as default browser, uninstaller Internet Explorer 11 (both are unnecessary based on the test on my VM, though)

4. removed all other Edge profiles, only leave the default profile, not signed on

5. removed all extensions in Edge

6. Clear ALL cache in Edge

7. Reset Edge settings to default

So my Edge is practically like fresh

8. make sure I don't have VPN, and internet connect is working

* make sure Edge works fine, close and restart ufile app, try again.

* Restart my laptop, and try again.

Nothing works so far.

oh my god. finally fixed it. @ufile team, please send this to your dev team, they may find a fix from code, at least give a meaningful error message and a tip.


find error message in event log

A fatal error occurred while creating a TLS client credential. The internal error state is 10013.


Windows+R, run "inetcpl.cpl"

go to Advanced > Scroll down to Security and note the TLS settings. Make sure check "Use TLS 1.2"

or, for most users, you can simply click "Restore advanced settings".

I tried this fix, but it didn't work for me. Am I to understand that there has been ZERO response from UFile to the people here saying they can't connect to the CRA? I am in an extremely difficult financial situation and I literally had to go without two meals to afford this software. I bought it because I've been using it since 2015 and I thought it would make this stressful chore easier for me. Instead, it's made it more stressful. I would like a refund, as I cannot file my taxes without being able to use Auto-fill.

If you cannot download / AFR (AutoFill Return) not responsive. It could be several things:
The government website is very busy - try again later.
If logging in with “Sign-in Partner login” try “CRA sign-in” (using CRA MyAccount).
You should also verify with the CRA if the account log-on is valid. 
• Your antivirus or firewall is preventing the download - temporarily disable to download.
• Could be your Internet Service Provider - then you need to restart the modem (or contact your ISP)
• Check computer time and date and language so the compute can synchronize with the CRA.
• Make sure your account access is up to date.
• If you have Windows 10 or 11, download “Microsoft Edge Webviewer” at the following link (it may not have been bundled in your version): https://go.microsoft.com/fwlink/p/?Linkid=2124703
• Use the most recent version of the “Edge” browser.

Check EDGE  browser Settings:
1. Type "Internet options" in the Windows search menu.
2. Click "Internet Options".
3. Click on "Advanced" tab.
4. Scroll to the Security section, then check Use TLS 1.2.
5. Click OK, then close Edge. TLS v1.2 is enabled on the next start of Edge.

Of note can also be effected by : Internet speed, computer memory/speed , network latency, CRA Server loads, anti-virus, firewall and the data within the download file.

make sure that the time clock on your computer is set to current time.  Apparently this is a CRA requirement for it to work.

My time was correct, but it still wasn't working. Turns out I refused to allow Windows to know my location when I set up my new laptop and set my timezone MANUALLY.

So I enabled location services then enabled the set time zone AUTOMATICALLY option. That fixed the problem for me.

Hello crow7730,

Thanks for the update.  Regarding location services :

-Enable location services 
    At the top right, click More. Settings.
    Click Privacy and security. Site Settings.
    Click Location.
    Choose the option you want as your default setting.

Microsoft Edge:
    Go to Start > Settings > Privacy > Location.
    Turn on Allow access to location on this device.
    Turn on Allow apps to access your location.
    Turn on Allow desktop apps to access your location if present.

Start by clicking the Apple symbol in the upper left-hand corner followed by System Preferences:
Then click Security & Privacy
Then click the Privacy tab
Click on the padlock in the bottom left-hand corner of the window. You will be asked to authenticate by entering your computer ID/password. Once entered, you will then be able to adjust your Location Services by checking the box next to Enable Location Services and ensuring location services are enabled specifically for Safari:
Click the lock again once done.
