File transfers

I’m having an issue where I can’t seem to send files through Spark. I have an Opefire 3.6.3 server installed with the file transfer proxy enbaled. I’ve found that I have a difficult time with file transfers on most every client except Pidgin. If anyone has any ideas as to why I’d appreciate it! It may be some settings on my server but I’m just not sure.

Thanks,

Doug
