It sounds like you're experiencing a connection issue with Exosphere, which can be frustrating. Let's go through some troubleshooting steps to help resolve this problem:

1. Check Network Configuration:

   • Ensure that both your PC and the IoTiny are on the same network. If you have two WLANs, make sure they are configured to allow communication between devices on both networks.
   • Verify that your network firewall or router settings are not blocking the necessary ports for Exosphere. The error message indicates a connection issue with the IP 24.83.13.218:42069, so ensure this is not being blocked.

2. Verify Internet Connection:

   • Make sure your PC has a stable internet connection. You can test this by browsing other websites or using online services.
   • If possible, try connecting your PC to a different network to see if the issue persists.

3. Update ARC and Exosphere:

   • Ensure you have the latest version of ARC installed. You can check for updates within the ARC software.
   • If there are any updates or patches for Exosphere, make sure they are applied.

4. Reconfigure Exosphere:

   • Double-check your Exosphere configuration settings. Ensure that the user credentials and other settings match what is required.
   • Re-add the user in the User Access tab, ensuring the username matches exactly with your Synthiam.com account.

5. Test with a Different Device:

   • If possible, try using a different PC or device to connect to Synthiam.com and submit a task. This can help determine if the issue is specific to your current PC.

6. Check Synthiam.com Status:

   • Occasionally, there might be server-side issues. Check Synthiam.com or their support channels to see if there are any known issues with Exosphere.

7. Contact Support:

   • If the issue persists, consider reaching out to Synthiam support directly with detailed information about the error and the steps you've taken. They may have additional insights or solutions.

If you need further assistance or have any questions about these steps, feel free to ask!

@athena @Synthiam Support , i double check my config but seems ok to me. My home pc uses win11. I did the same procedure on another PC with win 10 but same problem. I think we can eliminate an issue with a pc.  I did another test by connecting to synthiam.com with a linux Pc using LAN, no wifi , same problem. I dont know if it is important but i can not ping the ip-address listed in the error message 24.83.13.218. i can ping synthiam.com.

any idea ?

It seems like you've done a thorough job of testing across different devices and operating systems, which helps narrow down the issue. The fact that you can't ping the IP address listed in the error message (24.83.13.218) but can ping synthiam.com suggests that there might be a network routing issue or a firewall blocking the specific IP or port.

Here are a few additional steps you can take:

1. Check Firewall and Security Software:

   • Ensure that any firewall or security software on your network or PC is not blocking the IP address or the port (42069) used by Exosphere. You may need to add an exception for this IP and port.

2. Router Configuration:

   • Check your router settings to ensure that there are no restrictions or blocks on the IP address or port. Some routers have advanced security settings that might block certain types of traffic.

3. ISP Restrictions:

   • It's possible that your Internet Service Provider (ISP) is blocking the specific IP address or port. You can contact your ISP to inquire if there are any restrictions in place.

4. Traceroute:

   • Perform a traceroute to the IP address (24.83.13.218) to see where the connection is failing. This can provide insight into whether the issue is within your local network or further upstream.

5. Check Synthiam's Status:

   • Verify if there are any ongoing issues with Synthiam's servers or Exosphere service. You can check their website or contact their support for any known issues.

6. Use a VPN:

   • As a temporary workaround, try using a VPN to see if it allows you to connect to the Exosphere service. This can help bypass any network restrictions that might be in place.

7. Contact Synthiam Support:

   • Since you've already done extensive troubleshooting, it might be beneficial to contact Synthiam support directly with all the details of your issue. They may have additional insights or be able to check if there are any server-side issues affecting your connection.

If you have any further questions or need more assistance, feel free to ask!

I just checked on ping.eu/port-chk, it says that the port is closed.

If the port is reported as closed, it indicates that the connection attempt to the Exosphere service is being blocked or not reaching the server. Here are some steps you can take to address this issue:

1. Verify Port Forwarding:

   • Check your router settings to ensure that port forwarding is correctly configured for port 42069. This is necessary if your network setup requires it for external connections.

2. Check Firewall Settings:

   • Ensure that your firewall settings on both your PC and router are not blocking port 42069. You may need to add an exception for this port.

3. Contact Your ISP:

   • Some ISPs block certain ports by default. Contact your ISP to verify if port 42069 is being blocked and request that it be opened if necessary.

4. Use a Different Network:

   • If possible, try connecting your PC to a different network (e.g., a mobile hotspot) to see if the issue persists. This can help determine if the problem is specific to your current network.

5. Check Synthiam's Status:

   • Verify if there are any known issues with Synthiam's servers or Exosphere service. You can check their website or contact their support for updates.

6. Use a VPN:

   • As a temporary workaround, try using a VPN to see if it allows you to connect to the Exosphere service. This can help bypass any network restrictions that might be in place.

7. Contact Synthiam Support:

   • Since the port is closed, it might be beneficial to contact Synthiam support directly with all the details of your issue. They may have additional insights or be able to check if there are any server-side issues affecting your connection.

If you have any further questions or need more assistance, feel free to ask!

What provider are you using? We may have to add a request for the port to be available to you. Some providers limit what destination ports their customers can connect to. This limits the chances of malware and viruses from their perspective.

Actually - wait. That ip address is not correct. For some reason your DNS server has the IP address incorrect. Have you hardcoded an address in the hosts file? The hostname is exosphere.synthiam.com and its IP is currently 216.211.23.164

@dj sures I attached some photos, hope it helps. ARC runs on a win11 PC. I used 2 other pcs ( for testing purpose win10 WiFi and linux LAN) to connect to synthiam.com to open exosphere .  Win11 is new and i didnt change anything of the config. In the router, i have only one port forwarding 3184, i used for a remote UI connection. Do i need to add another port forwarding with 42069 ? dns config on my ARC pc win11.

Hmmm, I’m not certain where he’s getting that ip from. Let me think about it. I’m sure it’ll be something simple.
