Sources told the outlet there is “determination on both sides” to make the reunion happen. One insider reportedly said: “Nobody is pretending the wider family issues have been resolved, but this is about beginning with Charles and Harry. For the first time in a long time, there’s a genuine sense that reconciliation is within reach. Prince Harry’s team and the Palace have opened a line of communication, and there is every hope that father and son will see one another when the Duke returns to London.”
Rift With William Remains

While the possibility of a meeting with his father appears promising, insiders dismissed any suggestion of reconciliation between Harry and his brother, Prince William. “As for Harry and William, though, any chance of reconciliation between them has been rejected out of hand,” a source told the publication.
Harry, who serves as a long-standing patron of WellChild, is expected to present an award to an inspirational child, deliver a speech, and meet with seriously ill children and their families during the London event.
Neither Buckingham Palace nor representatives for the Duke have yet commented on the reported reunion.
