As I mentioned earlier, there seems to be 2 listings, for the same transponder, on 45E, according to lyngsat, which isn't unusual, except both are using the same polarity, Vertical, which is very unusual.
Both these transponders, 11550, are on different satellite beams, so intended for different markets, the first 11550 V 30000 DVB-S2 8PSK 3/4, is the Vivacom TV package, intended for Europe, the second 11550 V 28800 DVB-S2 8PSK 3/5 is listed on the India beam, so unavailable to most of us, in Europe, so I can't test it.
It isn't even listed, on many satellite sites, as they are more intended for the European market.
You could try editing your satellites.xml file, to alter the 45E listing, for 11550, to the details for Dialog TV, then try scanning, or try to get hold of a satellites.xml version for the India region, and see if this resolves the problem.
I can't think of it being a hardware, or software, problem, as other VU+ models, including my VU+ Duo 2, can handle most symbol rates, from feeds using 6660, or lower, to packages using 30000, and most in between.
There seem to be a number of members, on this forum, struggling with this transponder, in India, and have different versions, of the VU+ receiver. For those with different versions, like the VU+ Solo, or even the VU+ Duo 2, have you upgraded your bootloader, and any other upgrades, supplied by vuplus?
