I'd recommend Startup Grind - https://www.startupgrind.com/
Apart from being a place with an awesome community, it is a great platform to get some business perks and participate in various international events.
@rhea_reanoga sure, welcome :) And thank you for your question, as I also discovered new communities to join. Good luck on your entrepreneurial journey!
It depends on what you want to build if SaaS and digital goods are your game.

The entrepreneur Reddit is, in my opinion, not that valuable.
What I always recommend is to follow those who you deem as wise on LinkedIn or Twitter.
I'd like to recommend The Solopreneur Community on Facebook (https://www.facebook.com/groups/...). Full disclosure, it is hosted by my company, LifeStarr. But there is no selling/pitching allowed, just awesome solopreneurs helping each other. It's free as are the associated events.
Check out this leadership solopreneur community called SoloGrit - https://www.sologrit.com It's a community for solopreneurs that specialize in leadership roles like Fractional Executives, Consultants, Coaches, and Advisors. Great place for startup founder to get connected.
