I’m aware that accessing web srv process running in termux is in general working (I’m accessing radicale UI that way), my question was more about whenever there is any specific of cli syncthing that have impact on using web gui. If I understood your answer correctly, there is no issue with it. Thank you! Though it’s a pity, as I have hoped to get rid of using Termux (kinda powerful tool not really recommended for GrapheneOS users), but under such circumstances I will revise my decision especially as I couldn’t find non-termux replacement for radicale+DavX5 to get ics+vcf into Android PIM store.
