NOT SO FAST
There are still some possibilites (none of them are free unfortunately, except… ) :
For example you can pay for VPS, and in that you can go as low as 95 Indian rupees and possibly lower, with that, you will get custom blynk server running, free ssl certificates, unlimited “Blynk charge”, and you still got fully functional server, where you can get running for example your own webpage or for running other server applications as well as Domoticz and many others. Search for a “VPS server” (fun fact: VPS stands for VirtualPrivateServer, so it should not be needed to search VPS server, but people still call it like that, another is a LED diodes.) or you can try to find FREE VPS, but honestly, for me it was just waste of time as I was not able to find anything useful. You might be more lucky.
…except I can offer you a solution… sort of. As you might deduced already, I have VPS, and I am able to forward your ports outside of your niggard ISP to my VPS. I will let you do it for free, although, I can not guarantee you that my server will have 100% online time neither that there will be running forever, but if you want it as for test before you buy your own VPS, you can do it. I can help you with the configuration if you shall.
