I have been having this issue for the past week, reinstalling does not help. My dlog looks very much the same as in this post. Chrome is set as default browsers, there are no firewalls or anything else restricting the network traffic.
There are a number of troubleshooting steps to try in the link provided above. Please check through the advice that Vishal has given in the various threads.
I understand its a long read but there are many thing to try that can result in success.
I have gone through the threads and tried all the things listed. They do not help my case.
Ok please post the latest Simlink log here and we can take a look.
Bear in mind that its the weekend so we have limited support until Monday.

no worries, it has been broken for the last week for me, there is no immediate rush to fix it.
Can you make note of what you tried and the result? Its very important we understand what path you tried in order to eliminate those possibilities. Also, please start the sim and Simlink and send this log. It would be really nice to have the most updated set of logs for when both apps should be interacting with one and other.
To summarise advice;
Anti-Virus
- Temporarily disable this or add an explicit exemption for Simlink. HTTPS being blocked will affect Simlink discovery.
DNS
- Change this setting from Auto to specify DNS server(s). Typically the safest route is using Google (8.8.8.8 or 8.8.4.4) or Cloudflare (1.1.1.1)
VPN
- If you use a VPN, please disable this. Also, if you use something that filters ads, like PiHole, NextDNS or AdGuard, please disable these to test. If you are using a corporate grade router like something from Ubiquity (Unifi), please take a look at the filtering options here too.
System Clock
- It’s vitally important that your computer’s clock is synchronised to internet time. Right click your system clock on the taskbar and select:
- Adjust Date & Time → Confirm that the time and timezones are set automatically.
Following the guide, I completely reinstalled Simlink Connect, and removed any and all Navigraph settings files and folders that were left over from the previous installation before installing again.
I also ensured there are no proxy blocks in any settings files. There were not.
I have no Antivirus software.
My DNS is already set to 8.8.8.8 with 1.1.1.1 being the failover setting.
I do not use VPN.
The system clock uses NTP and is correct.
I do not understand why Simlink Connect requires authentication, when all it does is connect to the Simulator, which has its own authentication, and the Charts app, which also has its own authentication.
I have attached a log after having tried the above steps above - it is already available to you.
You mentioned you completely reinstalled Simlink however any other information it can give can help with investigating this issue. The more we can understand, the quicker this can be resolved.
Can you isolate your own network and tether/WiFi hotspot to your mobile data? This would be very helpful to see if there is some blocking going on upstream.

I would also recommend whitelising Simlink through Windows Security, regardless of whether or not you have Anti-virus installed.
Regarding Simlink needing to authenticate your account, unfortunately this is definitely a required function as it needs to access your account in order to display your ownship location on the Charts app.

I am really not sure what else I can add, the machine is a stock Windows install, it is only used for playing Windows games from XBox store and Steam. It was installed in 2020 as a Win10 machine and then eventually updated to Win11 when popups asked me to. I have not changed any settings away from defaults, it has auto updates enabled and seems to keep itself working, I generally just leave it to do its thing. My home network is exceptionally simple, there is a cable that comes out of the back of the PC that goes straight into the ISP provided router. That device also has next to 0 configuration options, I cannot even adjust the DHCP range. Again, I just let it do its thing and leave it alone.
Generally I get pretty good experience with the machine, it has certainly not had any apps fail to connect to something before. This app whitelisting is quite likely the most custom thing my Windows machine now has from stock, as I have not had to do anything like that for any other app.
I have added SimLink to the white list in Windows Security. I have also tried teathering through my phone’s 5G. Neither solution helped.
The new log file is pasted below, it is very similar to the old one:
[2026-07-14 16:06:22] [1.1.41.1805] [ERROR] OIDC_run ERROR:'Cannot connect to identity discovery endpoint.. Exception in call of initialize_oidc_client()
Identity server:https://identity.api.navigraph.com
[2026-07-14 16:06:22] [1.1.41.1805] [ERROR] LoginController::login_oidcError[8][Could not connect to Navigraph Identity Server]
After weeks of failing today it authenticated. I changed nothing.
Thats great to hear.
Outside of those basic checks and isolating your network using a mobile connection, its very difficult to say what the actual issue is. If its working now, it clearly was something ISP related.
Unfortunately it happens.
