yeah bitcoin is a very expensive clock.
Having the transaction appear in block explorers doesn't mean that it is necessarily valid, when it comes to the timestamp. The network consensus with BIP113 is that the timestamp has to be the median of the last 11 block which means that it can deviate from the actual time by 1 hour, and that explains why your transaction couldn't broadcast at 7PM and you could at 8PM. If you're looking to do nLocktime, you should set it an hour in advance.
The fact that the blockexplorer threw a non-final error basically shows that the transaction is still behind the unix time. I'm not sure why Blockcypher accepted it but if it didn't get propagated, then their timestamps logic could be wrong.

At 710pm...no luck in broadcast...tried around 8 and all went well!

I try to push on smartbit.com.au and I get PUSH TRANSACTION ERROR: 64: NON-FINAL
There's only 2 reasons I think this error could occur:
1. You added a space or extra character somewhere that it wasn't expecting so it couldn't parse it
2. It's just broken. I'm leaning towards the second.
3. Also was it definitely past the blockheight? The 10 minutes if you did use blockheight might be out as the 10 minutes is a targeted average.
There's also a chance the fee was too low. That seems to be a common error and a lot of nodes used to not hold.more than 20mb in their mempool (but I imagine these explorers could hold at least 128gb in their mempool without exceeding the capacity of a single ram chip.
I pushed it on blockstream now....and it really broadcast..I also see it in my wallet as well
https://blockstream.info/tx/7fde5a833eabc42b5f90d3a5a8015372e449d6749fa090c678a2f7746b76d007
And it shows everywhere!
But why earlier would https://live.blockcypher.com/btc/tx/7fde5a833eabc42b5f90d3a5a8015372e449d6749fa090c678a2f7746b76d007/

So I looked it up on blockchain and blockchair...and it never existed as they came up with nothing!
Tried again on blockcypher and I get

Ok so I made a new locktime for 240pm EST as follows...
I wanted to see if it would broadcast...and it did before the 10 minutes to broadcast arrived here
https://live.blockcypher.com/btc/tx/7fde5a833eabc42b5f90d3a5a8015372e449d6749fa090c678a2f7746b76d007/

I will try another one, but had to post this one..no idea what I am doing wrong..will give it a 30 min lead time this time.

It would appear that with the very large number of unconfirmed transactions over the last few days, that the "mempoolminfee" code got triggered... 
Note that the error you had in Electrum explicitly mentioned "mempool min fee"... and not the usual "min relay fee" etc:
Note that the error you had in Electrum explicitly mentioned "mempool min fee"... and not the usual "min relay fee" etc:
The electrum server you're sending it to wants a higher fee to be paid. Not sure why though since it says it's 2 sat per byte (maybe trying to. Help people not get transactions stuck with a custom script on that specific node).

So I took the raw data from electrum and went to qr.io and converted it to a qr code. Scanned and it matched the hex data perfectly. THAT problem is solved. Tomorrow will work on the time lock. Thanks again all
I also scanned qr code with qr code reader...and i get

Electrum uses base43 encoding for their QR codes.

I tried again an hour later and still same results.
Could you try it today too? I'm wondering if there were any issued with your PC clock or with the conversion of your local time to GMT by Electrum. 1610392963 (the locktime in the picture in OP) is January 11, 2021 7:22:43 PM GMT, your picture is showing 2:22:43 PM since there is 5 hour difference and if there were any issues there (such as your clock, timezone or bug in Electrum), only 1 hour waiting wouldn't be enough.
I just tried with a block number...and I am getting same issues. Why? The deposit I placed in Electrum wallet is unconfirmed....thats the only thing I can see that might be an issue..but I doubt it 
It can't be the unconfirmed UTXO, unless it's from a local transaction but it should produce a different error for a different issue.I've tried it in v4.0.9 testnet and it got rejected when it was broadcast before the set block height (as expected).
And then waited for the next block to come (same height as nLocktime) and it was successfully sent.
Maybe it's the server's node that you're connected to?
I tried again an hour later and still same results. I am using blockheight now as an experiment and see how that goes. But I want the time lock exact not guessing what the time might be.
You'll have some inaccuracy when using unix time as nlocktime, that is by design. nLocktime uses the median time past of the 11 blocks prior to the block that includes your transaction. As such, you might have to wait up to an hour before it can be relayed. Exact timing will not be possible.Your transaction appears to be rejected with non-final. Is the nlocktime specified smaller than the current block height? The nlocktime specifies that the current block height must be strictly greater than the nlocktime. As for the decoding on transaction, I'm aware that Blockchain.com appears to be bugged and can't process the raw transaction.

Could it be it's too close to the end time?

The electrum server you're sending it to wants a higher fee to be paid. Not sure why though since it says it's 2 sat per byte (maybe trying to. Help people not get transactions stuck with a custom script on that specific node).
Ok..but why am I getting errors on the websites? I am trying to broadcast it on btc.com and also on blockchain.com
Edit..whoever gets this in the future should be able to transmit anywhere thats why I am trying outside sources

Ok. I made an Electrum nLocktime transaction for a certain date in the future instead of block heoight.....yet when the time came and past I was not able to broadcast on Electrum or on a blockchain website. Can someone please let me know what exactly is the issue? Thanks
I made a transaction timelock for the 11th January 2011 222pm
I used the following website to decode...it was the only one able to
https://btc.com/tools/tx/decode
I tried the same on https://www.blockchain.com/btc/decode-tx
And I got this error
SO when the time came and went past the broadcast..I tried and these are the results.
On btc.com
On blockchain.com Code: -26, Error: non-final
and this on electrum itself
