Couldn't open connection to server

[MILSnIO]

Since update I have continually gotten this pop up message with no explanation as to why.

I had this same issue, followed these steps and it worked for a week. The issue came back, so I read more and was told to clear the cache partition, did that and I am still getting the message. Any suggestions?

I did what you said and now it says can't connect to server instead of couldn't connect to server but it's still doing it. Do you have any idea why it's doing this or how to fix it?

@user3wdZtaV3Yt Have you tried clearing the cache partition on your phone. Here are the steps. 

1. Turn off the device.
2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
3. When the Android logo displays, release all three keys.
4. An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

Not true. I tried Reset Network Settings and it did not fix. Samsung S9

That did not solve it for me! Are there any other suggestions?

This worked for all of 5 minutes then it went right back to spamming "Cannot connect to server" when texting anyone.
