Pete I just doubled checked and I have uploaded the above sketch. The time still shows up on SM.
The time is wrong however and it is not my location time, nor is it the time in Singapore, which is the server region I am connecting. Strange!

Looks like that is produced by the library when you use SSL, but I’ve never seen that before.
Can you take this device offline.
I’ll upload your sketch and see if I can force a connection to the DGP1 server by using the server suffix, then see if I have the same issues.
Pete.

As you can see, it’s connecting to SPG1 and should be showing as Online on your web console and timeline.
I’m getting a 1ms ping from London to Singapore, which is similar to your SSL ping times.
It’s currently been online for over 30 minutes without any issues, the latest serial monitor output was…
13:33:20.908 -> [2175535] <[06|00]2[00|00]

13:34:06.262 -> [2220886] >[00|00]3[00|C8]
Your device timeline should confirm these numbers.
I’ll keep monitoring it, but clearly it’s already been running longer than it does for you.
It’s obviously not a Blynk account or server issue, as I’m using your account which lives on the SPG1 server. It’s not a code issue, as we’re running the same code.
That leaves hardware or internet as the culprit.
My money is on it being an issue with your internet, or a WAN issue that is local to you, and outside of Blynk’s control.

Pete I really do appriciate you taking the time to debug this issue with me. Your help has narrowed down things and brought us to 2 possible causes, hardware or ISP/router setup.
It has remained connected for much longer than when I attemped.
It is very unlikely to be hardware as I’ve tried the same sketch on some other D1 mini boards and ESP32s, same results, so I guess at this point all heads turn to either my ISP or router, as you mensioned.
Any changes I could make to my router’s settings that could help prevent such disconnections from occuring?
One thing I can try is connecting the board to a router with no other device connected. At this point anything is worth a try?
I suspect that the issue lies downstream from the router, probably with your ISP.
Pete.
It’s still running fine without any disconnections, so I’m going to take the Wemos offline because I think we’ve proven the point.
I’ll flash the Wemos with a blank sketch so that it doesn’t connect next time I plug it in, to avoid any confusion at your end.
Pete.

Thank you Pete
I will try a couple of things on my router and if everything fails, I’ll speak to my ISP.

A little bit of positive news,
My other D1 mini which was running my main sketch was online for the longest it has been for awhile!
Almost an entire day without a single disconnect. It unfortunately went offline 1 and a half hours ago.
I hope to be free this weekend to have a look at my router settings…
Edit: The Blynk protocol is non-edgent, port 80 sketch…
Update:
Still disconnecting from Blynk servers and SM output is continous “Connect to blynk.cloud:80”
My last idea is to continously check if the board is connected to blynk servers and if it is not, reboot the board.
if(!Blynk.connected())
{
ESP.restart();
}
This code doesn’t seem to work as the board does automatically reboot when the “(!Blynk.connected()” is met…
What are options 
I don’t understand this statement.
I think the bottom line is to establish what the primary cause of the issue is - and I suspect it’s your ISP - and fix that problem.
Pete.
Apologies for the typo.
I meant the board does not reboot when the “(!Blynk.connected())” condition is met. It appears to return “true” even though it’s attempting to reconnect to the server. I read another discussion of the same issue.
I spoke to my ISP, unsurprisingly the technician didn’t have a clue what Blynk is and I had to briefly explain it. After a good 10mins of on and off hold, they said there are no restrictions in place for Blynk and any other IoT platforms.
They then suggested the same old restart the router and try again….
I agree with you Pete about finding the root cause instead of taking a short cut. I am ashamed to come to a point where I still haven’t solved this and my last option being to add a line of code to patch the bug….
I’ve even thought of adding an arduino with a relay to reboot the wemos every “X” hours by interrupting the power…
I’m desperate to keep the device running and online continuously without me having to reset it.
This week I will try connecting the wemos to its own router (only device connected). Hoping for positive results….
You should probably post the code you are using.
It might be worth reading this, then having another chat with the technician…
Pete.

Pete I made an interesting discovery.
I disconnected the fiber cable from the router to simulate a internet blackout and the wemos attempts to connect to blynk.cloud (as expected). However, when I reconnect the fiber cable back to the router and confirm on my phone that the internet connection as been restored, the wemos however still attemps to connect to blynk.cloud.
So what I believe is happening is that theres brief internet blackout, and the wemos gets stuck on a loop trying to establish a connection with the sever, even after the internet has been restored.
So this comfirms that it has nothing to do with my ISP blocking Blynk servers. The wemos is simply unable to reconnect to blynk server on its own after an internet blackout.
Any suggestion on how I can fix this?
Please see attached SM output and code below
At timestamp 17:52:47.361, the board has succefully connected to the server.
At timestamp 18:05:51.544, I unplugged the fiber line to simulate a internet blackout
At timestamp 18:07:03.074, I reconnected the fiber line and comfirmed internet is restored

}You need to stop using Blynk.begin, and switch to managing your own WiFi connection and using Blynk.config and Blynk.connect.
You then need to have timed functions that check if you’re still connected to WiFi and to Blynk, and that re-connect where necessary.

Noted. I refered to this discussion and code and implemented certain parts for testing. So far so good, the board reboots when it detects a loss of connection to the servers. I will continue testing and hopefully the issue has been solved.
Good news!
The issue appears to be solved and the board has stayed online for 2 days. Within the 2 days it has lost connection to the server, but after implementing parts from the above attached discussion, the board automatically reboots and restores connection to the server, thus fixing the issue.
I am really happy with this result. My project is now online and everything is working as expected.
Its been a month of diagnosing this simple matter but I really appriciate your help Pete. Thank you.
Heres a summary for anyone new of the issue I faced.
My D1 mini would go offline multiple times a day and would not reconnect to the Blynk server automatically. After concluding that it wasn’t my code nor my ISP blocking Blynk, I discovered that my internet connection would have multiple black outs per day. Therefore when a blackout occurs, the board looses connection to the server (expected), however when the internet connection is restored, the board continues to “Connecting to Blynk.cloud:80” till I manually reboot it.
You do t need to reboot the server, just re-establish the Blynk and/or WiFi connection.
Pete.
