Hi there! I’m sorry to hear you’re experiencing a network error while trying to log in to DUPR. Let’s work together to try and resolve this issue.

Since you've mentioned that you've already tried all the suggested solutions, let’s dive a little deeper. Here are some steps that can often help in these situations:

1. Check Internet Connection: Make sure you're connected to the internet and try switching between Wi-Fi and mobile data. Sometimes, switching networks can help resolve connection issues.

2. Clear Cache and Data: Sometimes, clearing the app's cache or data can resolve login issues:
- Go to Settings on your device.
- Tap on Apps or Application Manager.
- Find and select DUPR.
- Select Storage and then tap Clear Cache. If that doesn’t help, you can also select Clear Data, but be aware that this may reset any local settings.

3. Update the App: Ensure that you have the latest version of the DUPR app. Check the Google Play Store for any available updates and install them if necessary.

4. Restart Your Device: Sometimes, a simple restart of your device can resolve network-related issues.

5. Examine Network Settings: Check your device’s network settings for any issues. Make sure that the correct APN (Access Point Name) is set if you are using mobile data.

6. Use a VPN: If you suspect network restrictions might be affecting your access, try using a VPN to see if that resolves the issue.

If none of these steps work, it could possibly be a server-side issue or a glitch with your account. I recommend reaching out to DUPR support directly at [email protected] for specialized assistance.
